1 Introduction
The importance of nonlinear evolution equations (NLEEs) isnow well established since these equations arise in variousareas of science and engineering especially in fluid mechan-ics biology plasma physics solid-state physics optical fibersbiophysics and so on As a key problem finding theiranalytical solutions is of great importance and is actuallyexecuted through various efficient and powerful methodssuch as the Exp-function method [1ndash4] the tanh-functionmethod [5 6] the homogeneous balance method [7 8]the (1198661015840119866)-expansion method [9ndash16] the Hirotarsquos bilineartransformationmethod [17 18] the Backlund transformationmethod [19] the inverse scattering transformation [20] theJacobi elliptic function method [21] the modified simpleequation method [22ndash24] and so on
Theobjective of this paper is to look for new study relatingto the MSE method via the well-recognized GZK-BBM
equation and right-handed nc-Burgersrsquo equation and estab-lish the originality and effectiveness of the method
The paper is organized as follows in Section 2 we givethe description of the MSE method In Section 3 we usethis method to the nonlinear evolution equations pointed outabove and in Section 4 conclusions are given
2 Description of the MSE Method
Suppose the nonlinear evolution equation is in the followingform
119865 (119906 119906119905 119906119909 119906119909119909 119906119905119905 ) = 0 (1)
where 119865 is a polynomial of 119906(119909 119905) and its partial derivativeswherein the highest order derivatives and nonlinear terms areconcernedThemain steps of theMSEmethod [22ndash24] are asfollows
2 ISRNMathematical Physics
Step 1 The traveling wave transformation
119906 (119909 119905) = 119906 (120585) 120585 = 119909 plusmn 120584119905 (2)
permits us to reduce (1) into the following ordinary differen-tial equation (ODE)
119875 (119906 1199061015840 11990610158401015840 ) = 0 (3)
where 119875 is a polynomial in 119906(120585) and its total derivativeswherein 1199061015840(120585) = 119889119906119889120585
Step 2 We suppose the solution of (3) is of the form
119906 (120585) =
119873
sum119896=0
119862119896[Φ1015840 (120585)
Φ (120585)]
119896
(4)
where 119862119896(119896 = 0 1 2 3 ) are arbitrary constants to be
determined such that 119862119873= 0 and Φ(120585) is an unidenti-
fied function to be determined afterwards In Exp-functionmethod (1198661015840119866)-expansion method tanh-function methodJacobi elliptic function method and so forth the solutionis offered in terms of some predefined functions but inthe MSE method Φ is not predefined or not a solution ofany predefined differential equation Therefore some freshsolutions might be found by this method This is the meritof the MSE method
Step 3 We determine the positive integer 119873 come out in(4) by considering the homogeneous balance between thehighest order derivatives and the highest order nonlinearterms occurring in (3)
Step 4 We compute all the required derivatives 1199061015840 11990610158401015840 and substitute (4) and the derivatives into (3) and then weaccount for the functionΦ(120585) As a result of this substitutionwe get a polynomial of (Φ1015840(120585)Φ(120585)) and its derivatives Inthis polynomial we equate all the coefficients to zero Thisprocedure yields a system of equations whichever can besolved to find 119862
119896and Φ(120585)
3 Applications
31 The GZK-BBM Equation In this subsection we will usethe MSE method to look for the exact solutions and then thesolitary wave solutions to the GZK-BBM equation
119906119905+ 119906119909+ 120572(119906
3)119909+ 120573(119906
119909119905+ 119906119910119910)119909= 0 (5)
where 120572 and 120573 are nonzero constantsUsing traveling wave transformation
119906 = 119906 (119909 119910 119905) 120585 = 119909 + 119910 minus 120584119905 119906 (119909 119910 119905) = 119906 (120585)
(6)
(5) reduces to the following ODE
minus1205841199061015840+ 1199061015840+ 120572(119906
3)1015840

= 0 (7)
Integrating (7) with respect to 120585 we obtain
(1 minus 120584) 119906 + 1205721199063+ 120573 (1 minus 120584) 119906
10158401015840= 0 (8)
Balancing the highest order derivative 11990610158401015840 and nonlinear term1199063 we obtain119873 = 1
Therefore the solution (4) turns into the following form
119906 (120585) = 1198620+ 1198621(Φ1015840
Φ) (9)
where 1198620and 119862
1are constants such that 119862
1= 0 and Φ(120585) is
an unidentified function to be determined It is easy to findthat

Substituting the values of 119906 11990610158401015840 and 1199063 from (9)ndash(12) into (8)and then equating the coefficients of Φ0 Φminus1 Φminus2 and Φminus3to zero we obtain

Φ10158401015840= minus119897 (18)
where 119897 = (31205721198620

Integrating (18) we obtain

(120585) = 1198881119890minus119897120585 (19)
where 1198881is a constant of integration
And from (15) and (19) we obtain
Φ1015840= minus119898119890
minus119897120585 (20)
where119898 = 120573(120584 minus 1)119888112057211986201198621
ISRNMathematical Physics 3
Integrating (20) with respect to 120585 we obtain
Φ (120585) = 1198882+119898
119897119890minus119897120585 (21)
where 1198882is a constant of integration
Substituting the value ofΦ andΦ1015840 into solution (9) yields
119906 (120585) = 1198620+ 1198621(minus119897119898119890minus119897120585

) (22)
Case 1 When 1198620= 0 solution (22) collapses and hence this
case is rejected
Case 2 When 1198620= plusmnradic(120584 minus 1)120572 and 119862
1= plusmnradic2120573(120584 minus 1)120572
substituting the values of1198620and119862
1into (22) and simplifying
we obtain the exact solutions
119906 (119909 119910 119905) = plusmn radic(120584 minus 1
120572)
times 1 minus21205731198881exp (plusmnradic2120573 (119909 + 119910 minus 120584119905))

(23)
Since 1198881and 1198882are arbitrary constants therefore if we set 119888
2=
11988812 the exact solution (23) turns out to the following solitary
wave solutions
119906 (119909 119910 119905) = plusmnradic(120584 minus 1
120572) tanh(radic1
2(119909 + 119910 minus 120584119905)) (24)
when 120573 = 1 On the other hand if 120573 = minus1 solution (23) turnsinto
119906 (119909 119910 119905) = plusmnradic(120584 minus 1
120572) coth(radic1
2(119909 + 119910 minus 120584119905)) (25)
In particular when 120572 = 1 and 120584 = 4 solutions (24) and (25)convert to
119906 (119909 119910 119905) = plusmnradic3 tanh(radic12(119909 + 119910 minus 4119905)) (26)
119906 (119909 119910 119905) = plusmnradic3 coth(radic12(119909 + 119910 minus 4119905)) (27)
respectively
For 119910 = 0 the solution 119906(119909 119910 119905) presented in (26) issketched in Figure 1
Again for 119910 = 0 the solution 119906(119909 119910 119905) presented in (27)is sketched in Figure 2
The MSE method is applied to investigate solitary wavesolutions to the GZK-BBM equation and obtained solutionswith free parameters involving the known solutions in theopen literature Obviously we might choose the values of thearbitrary constants 119888
1and 1198882equal to other values resulting
in diverse solitary shapes The free parameters imply somephysical meaningful results in gravity water waves in thelong-wave regime

Using traveling wave transformation (2) (28) is reduced tothe following ODE
11990610158401015840+ 2119906119906
1015840+ 1205841199061015840= 0 (29)
Integrating (29) with respect to 120585 and setting the constant ofintegration to zero we obtain
1199061015840+ 1199062+ 120584119906 = 0 (30)
Balancing the highest order derivative and nonlinear termwe obtain119873 = 1
Therefore solution (4) becomes

Executing the parallel course of action which is described inSection 31 we obtain

Solving (32) and (34) we obtain 1198620= 0 minus120584 and 119862

since 1198621= 0 respectively
Case 1 When 1198620= 0 and 119862
1= 1 and solving (33) we receive
the value of Φ and substituting the value of Φ into (31) weobtain the following exact solution
119906 (119909 119905) =120584 1198881exp (minus120584 (119909 minus 120584 119905))

(35)
where 1198881and 1198882are constants of integrationTherefore we can
make choices at random the parameters 1198881and 1198882 if we choose
1198881= 120584 and 119888
2= 1 the exact solution (35) turns into the under

And if 1198881= minus120584 and 119888

Case 2 When1198620= minus120584 and solving (33) we get the value ofΦ
and substituting this value into (31) we obtain the subsequentexact solution

We can arbitrarily pick the parameters 1198881and 1198882 Therefore
exact solution (38) turns into the following solitary wavesolutions

Step 1 The traveling wave transformation
119906 (119909 119905) = 119906 (120585) 120585 = 119909 plusmn 120584119905 (2)
permits us to reduce (1) into the following ordinary differen-tial equation (ODE)
119875 (119906 1199061015840 11990610158401015840 ) = 0 (3)
where 119875 is a polynomial in 119906(120585) and its total derivativeswherein 1199061015840(120585) = 119889119906119889120585
Step 2 We suppose the solution of (3) is of the form
119906 (120585) =
119873

119862119896[Φ1015840 (120585)
Φ (120585)]

(4)
where 119862119896(119896 = 0 1 2 3 ) are arbitrary constants to be
determined such that 119862119873= 0 and Φ(120585) is an unidenti-
fied function to be determined afterwards In Exp-functionmethod (1198661015840119866)-expansion method tanh-function methodJacobi elliptic function method and so forth the solutionis offered in terms of some predefined functions but inthe MSE method Φ is not predefined or not a solution ofany predefined differential equation Therefore some freshsolutions might be found by this method This is the meritof the MSE method
Step 3 We determine the positive integer 119873 come out in(4) by considering the homogeneous balance between thehighest order derivatives and the highest order nonlinearterms occurring in (3)
Step 4 We compute all the required derivatives 1199061015840 11990610158401015840 and substitute (4) and the derivatives into (3) and then weaccount for the functionΦ(120585) As a result of this substitutionwe get a polynomial of (Φ1015840(120585)Φ(120585)) and its derivatives Inthis polynomial we equate all the coefficients to zero Thisprocedure yields a system of equations whichever can besolved to find 119862
119896and Φ(120585)

31 The GZK-BBM Equation In this subsection we will usethe MSE method to look for the exact solutions and then thesolitary wave solutions to the GZK-BBM equation

119909119905+ 119906119910119910)119909= 0 (5)
where 120572 and 120573 are nonzero constantsUsing traveling wave transformation
119906 = 119906 (119909 119910 119905) 120585 = 119909 + 119910 minus 120584119905 119906 (119909 119910 119905) = 119906 (120585)
(6)
(5) reduces to the following ODE

= 0 (7)
Integrating (7) with respect to 120585 we obtain
(1 minus 120584) 119906 + 1205721199063+ 120573 (1 minus 120584) 119906
10158401015840= 0 (8)
Balancing the highest order derivative 11990610158401015840 and nonlinear term1199063 we obtain119873 = 1
Therefore the solution (4) turns into the following form
119906 (120585) = 1198620+ 1198621(Φ1015840
Φ) (9)
where 1198620and 119862
1are constants such that 119862
1= 0 and Φ(120585) is
an unidentified function to be determined It is easy to findthat

Substituting the values of 119906 11990610158401015840 and 1199063 from (9)ndash(12) into (8)and then equating the coefficients of Φ0 Φminus1 Φminus2 and Φminus3to zero we obtain

where119898 = 120573(120584 minus 1)119888112057211986201198621
ISRNMathematical Physics 3
Integrating (20) with respect to 120585 we obtain
Φ (120585) = 1198882+119898
119897119890minus119897120585 (21)
where 1198882is a constant of integration
Substituting the value ofΦ andΦ1015840 into solution (9) yields
119906 (120585) = 1198620+ 1198621(minus119897119898119890minus119897120585

Case 1 When 1198620= 0 solution (22) collapses and hence this
case is rejected
Case 2 When 1198620= plusmnradic(120584 minus 1)120572 and 119862
1= plusmnradic2120573(120584 minus 1)120572
substituting the values of1198620and119862
1into (22) and simplifying
we obtain the exact solutions

(23)
Since 1198881and 1198882are arbitrary constants therefore if we set 119888

11988812 the exact solution (23) turns out to the following solitary
wave solutions

Using traveling wave transformation (2) (28) is reduced tothe following ODE
11990610158401015840+ 2119906119906
1015840+ 1205841199061015840= 0 (29)
Integrating (29) with respect to 120585 and setting the constant ofintegration to zero we obtain
1199061015840+ 1199062+ 120584119906 = 0 (30)
Balancing the highest order derivative and nonlinear termwe obtain119873 = 1
Therefore solution (4) becomes

since 1198621= 0 respectively
Case 1 When 1198620= 0 and 119862
1= 1 and solving (33) we receive
the value of Φ and substituting the value of Φ into (31) weobtain the following exact solution

make choices at random the parameters 1198881and 1198882 if we choose
1198881= 120584 and 119888

Case 2 When1198620= minus120584 and solving (33) we get the value ofΦ

Integrating (20) with respect to 120585 we obtain
Φ (120585) = 1198882+119898
119897119890minus119897120585 (21)
where 1198882is a constant of integration
Substituting the value ofΦ andΦ1015840 into solution (9) yields
119906 (120585) = 1198620+ 1198621(minus119897119898119890minus119897120585

) (22)
Case 1 When 1198620= 0 solution (22) collapses and hence this
case is rejected
Case 2 When 1198620= plusmnradic(120584 minus 1)120572 and 119862
1= plusmnradic2120573(120584 minus 1)120572
substituting the values of1198620and119862
1into (22) and simplifying
we obtain the exact solutions

(23)
Since 1198881and 1198882are arbitrary constants therefore if we set 119888
2=
11988812 the exact solution (23) turns out to the following solitary
wave solutions
119906 (119909 119910 119905) = plusmnradic(120584 minus 1
120572) tanh(radic1
2(119909 + 119910 minus 120584119905)) (24)
when 120573 = 1 On the other hand if 120573 = minus1 solution (23) turnsinto
119906 (119909 119910 119905) = plusmnradic(120584 minus 1
120572) coth(radic1
2(119909 + 119910 minus 120584119905)) (25)
In particular when 120572 = 1 and 120584 = 4 solutions (24) and (25)convert to
119906 (119909 119910 119905) = plusmnradic3 tanh(radic12(119909 + 119910 minus 4119905)) (26)
119906 (119909 119910 119905) = plusmnradic3 coth(radic12(119909 + 119910 minus 4119905)) (27)
respectively
For 119910 = 0 the solution 119906(119909 119910 119905) presented in (26) issketched in Figure 1
Again for 119910 = 0 the solution 119906(119909 119910 119905) presented in (27)is sketched in Figure 2
The MSE method is applied to investigate solitary wavesolutions to the GZK-BBM equation and obtained solutionswith free parameters involving the known solutions in theopen literature Obviously we might choose the values of thearbitrary constants 119888

in diverse solitary shapes The free parameters imply somephysical meaningful results in gravity water waves in thelong-wave regime

Using traveling wave transformation (2) (28) is reduced tothe following ODE
11990610158401015840+ 2119906119906
1015840+ 1205841199061015840= 0 (29)
Integrating (29) with respect to 120585 and setting the constant ofintegration to zero we obtain
1199061015840+ 1199062+ 120584119906 = 0 (30)
Balancing the highest order derivative and nonlinear termwe obtain119873 = 1
Therefore solution (4) becomes
119906 (120585) = 1198620+ 1198621(Φ1015840

since 1198621= 0 respectively
Case 1 When 1198620= 0 and 119862
1= 1 and solving (33) we receive
the value of Φ and substituting the value of Φ into (31) weobtain the following exact solution

1198881= 120584 and 119888

4 Conclusions
Themodified simple equationmethod presented in this paperhas been successfully implemented to find the exact and thesolitary wave solutions for NLEEs via the GZK-BBM andright-handed nc-Burgersrsquo equation The method offers solu-tions with free parameters that might be important to explainsome intricate physical phenomena Some special solutionsincluding the known solitary wave solution are originatedby setting appropriate values for the parameters Comparedto the currently proposed method with other methods suchas the (1198661015840119866)-expansion method the Exp-function methodand the tanh-function method we might conclude that theexact solutions to (5) and (28) can be investigated usingthese methods with the help of the symbolic computationalsoftware such as Mathematica and Maple to facilitate thecomplex algebraic computations On the other hand viathe proposed method the exact and solitary wave solutionsto these equations have been achieved without using any
