We developed some basic theory of characteristic zero modular representations of q-Schur algebras. We described a basis of the q-Schur algebra in terms of the relative norm which was first introduced ...

Fusion systems have emerged as a powerful conceptual framework that encapsulates the conjugation relationships among p-subgroups of finite groups. This categorical approach not only unifies aspects of ...

In recent years, motivic techniques have been applied in several branches of representation theory, for example in geometric and modular representation theory. The goal of this workshop is to bring ...

A well-known theorem of Ken Ribet asserts that, under certain assumptions, a modular form (mod $\ell $) on $\Gamma _{0}(N)$ can be "lifted" to yield a newform on $\Gamma _{0}(N\ell)$ with the same ...
