A proof of the Murnaghan--Nakayama rule using Specht modules and tableau combinatorics
Jasdeep Kochhar, Mark Wildon
The Murnaghan--Nakayama rule is a combinatorial rule for the character values of symmetric groups. We give a new combinatorial proof by explicitly finding the trace of the represen…

Endomorphism Rings of Some Young Modules
Jasdeep Singh Kochhar
Let be the symmetric group acting on letters, be a field of characteristic 2 and and be partitions of in at most two parts. Denote the permutation module…
