On signed -Kostka matrices
Eugenio Giannelli, Kay Jin Lim
We show that the signed -Kostka numbers depend just on -Kostka numbers and the multiplicities of projective indecomposable modules in certain signed Young permutation modules…
Jantzen filtration of Weyl modules, product of Young symmetrizers and denominator of Young's seminormal basis
Ming Fang, Kay Jin Lim, Kai Meng Tan
Let be a connected reductive algebraic group over an algebraically closed field of characteristic , denote the Weyl module of of highest weight and $ι_{λ,μ}…
A note on the signature representations of the symmetric groups
Kay Jin Lim, Jialin Wang
For a partition λ and a prime p, we prove a necessary and sufficient condition for there exists a composition δ such that δ can be obtained from λ after rearrangement and all the p…
On the Brauer constructions and generic Jordan types of Young modules
Yu Jiang, Kay Jin Lim, Jia Lin Wang
Let p be a prime number. We study the dimensions of Brauer constructions of Young and Young permutation modules with respect to p-subgroups of the symmetric groups. They depend onl…
The Schur functor on tensor powers
Kay Jin Lim, Kai Meng Tan
Let be a left module for the Schur algebra , and let . Then is a -bimodule, where the symmetric group $\…
Specht modules with abelian vertices
Kay Jin Lim
In this article, we consider indecomposable Specht modules with abelian vertices. We show that the corresponding partitions are necessarily -cores where is the characteris…
