Some Restriction Coefficients for the Trivial and Sign Representations
Sridhar P. Narayanan, Digjoy Paul, Amritanshu Prasad +1
We use character polynomials to obtain a positive combinatorial interpretation of the multiplicity of the sign representation in irreducible polynomial representations of $GL_n(\ma…

On Quasi Steinberg characters of Symmetric and Alternating groups and their Double Covers
Digjoy Paul, Pooja Singla
An irreducible character of a finite group is called quasi -Steinberg character for a prime if it takes a nonzero value on every -regular element of . In this arti…

Tableau Correspondences and Representation Theory
Digjoy Paul, Amritanshu Prasad, Arghya Sadhukhan
We deduce decompositions of natural representations of general linear groups and symmetric groups from combinatorial bijections involving tableaux. These include some of Howe's dua…
