Representation Theory of Finite Groups and theFactorization of Stability Polynomials of RelativeEquilibria in Celestial Mechanics

PhD from University of Minnesota (2001), Post-doctorate at the Bureau desLongitudes, Observatoire de Paris (2002) and Visiting professorships atWilfrid Laurier University (2010, 2011). Professor at Universidade Federal dePernambuco, Brazil, since 2002. Main research interests: Celestial Mechanics,especially central configurations and relative equilibria, and MathematicalPhysics.

The representation theory of finite groups provides tools for factorizing the characteristicpolyonomials of the matrices which appear when one studies the linear stability ofsymmetrical relative equilibria of the N-body problem. Such factorizations go back to thework of J. C. Maxwell on the nature and stability of Saturn rings, and it is interesting tonotice that Maxwell's work appeared decades before the pioneering works of Frobeniusand Burnside on group representation theory. In the talk we will present the basicconcepts which permit to understand and systematize Maxwell's factorization, andprovide a view on how to proceed for general symmetric relative equilibria.
