Torsion pairs and Ringel duality for Schur algebras

Karin Erdmann, Stacey Law

Let $A$ be a finite-dimensional algebra over a field of characteristic $p > 0$ . We use a functorial approach involving torsion pairs to construct embeddings of endomorphism algebras…

Sylow branching coefficients and a conjecture of Malle and Navarro

Eugenio Giannelli, Stacey Law, Jason Long +1

We prove that a finite group $G$ has a normal Sylow $p$ -subgroup $P$ if, and only if, every irreducible character of $G$ appearing in the permutation character $(1_{P})^{G}$ with…

Sylow branching coefficients for symmetric groups

Eugenio Giannelli, Stacey Law

Let $p \geq 5$ be a prime and let $n$ be a natural number. In this article we describe the irreducible constituents of the induced characters $ϕ ⏐ ↑^{S_{n}}$ for arb…

On permutation characters and Sylow $p$ -subgroups of $S_{n}$

Eugenio Giannelli, Stacey Law

Let $p$ be an odd prime and let $n$ be a natural number. In this article we determine the irreducible constituents of the permutation module induced by the action of the symmetric…

On the $p^{'}$ -subgraph of the Young graph

Eugenio Giannelli, Stacey Law, Stuart Martin

Let $p$ be a prime number. In this article we study the restriction to $S_{n - 1}$ of irreducible characters of degree coprime to $p$ of $S_{n}$ . In particular, w…
