Irreducible restrictions of spin representations of symmetric and alternating groups

Alexander Kleshchev, Lucia Morotti, Pham Huu Tiep

Let $F$ be an algebraically closed field and $G$ be an almost quasi-simple group. An important problem in representation theory is to classify the subgroups $H < G$ and $\ma…

A reduction theorem for the Feit conjecture

Robert Boltje, Alexander Kleshchev, Gabriel Navarro +1

We prove that if all the simple groups involved in a finite group $G$ satisfy the `inductive Feit condition', then Walter Feit's conjecture from 1980 holds for $G$ . In particular,…
