Uma breve introdução à Teoria de Brauer, enfatizando aspectos funcionais que permitem uma extensão natural para grupos profinitos. Baseado no trabalho conjunto com Peter Symonds.

Two methods for calculating inner products of Schur functions in terms of outer products and plethysms are given and they are easy to implement on a machine. One of these is derived from a recent analysis of the SO(8) ...

We investigate the possibility of interpreting the degeneracy of the genetic code, i.e., the feature that different codons (base triplets) of DNA are transcribed into the same amino acid, as the result of a symmetry breaking ...

The trajectory of energy is modeled by the solution of the Eikonal equation, which can be solved by solving a Hamiltonian system. This system is amenable of treatment from the point of view of the theory of differential ...

We prove that a polar orthogonal representation of a real reductive algebraic group has the same closed orbits as the isotropy representation of a pseudo-Riemannian symmetric space. We also develop a partial structural ...

This paper is an introduction to the fascinating world of Soergel bimodules and it should be accessible to a broad audience. We aim to help the reader feel comfortable with Soergel bimodules and to explain some of the ...
