%0 Journal Article %T Character formulae for classical groups %A P. E. Frenkel %J Mathematics %D 2005 %I arXiv %X We give formulae relating the value of an irreducible character of a classical group at a matrix to entries of powers of the matrix. This yields a far-reaching generalization of a result of J. L. Cisneros-Molina concerning the $GL_2$ case. %U http://arxiv.org/abs/math/0511199v1
