Stiefel-Whitney classes for symmetric groups
Sujeet Bhalerao, Jyotirmoy Ganguly, Steven Spallone
We prove several results about Stiefel-Whitney Classes (SWCs) of representations of . First, each SWC is polynomial in the character values of at involutio…

Kronecker Coefficients and Simultaneous Conjugacy Classes
Jyotirmoy Ganguly, Digjoy Paul, Amritanshu Prasad +2
A Kronecker coefficient is the multiplicity of an irreducible representation of a finite group in a tensor product of irreducible representations. We define Kronecker Hecke alg…

Divisibility of Character Values of Representations of Coxeter Groups
Jyotirmoy Ganguly, Rohit Joshi
Let be a positive integer. We study the proportion of irreducible characters of infinite families of irreducible Coxeter groups whose values evaluated on a fixed element ar…
