Young Modules and Schur algebras
Moriah Elkin, Peter Webb
We compute explicitly the submodule structure of the Young modules for symmetric groups over fields of characteristic 2, when . We use this information to compute th…
Bilinear forms on Grothendieck groups of triangulated categories
Peter Webb
We extend the theory of bilinear forms on the Green ring of a finite group developed by Benson and Parker to the context of the Grothendieck group of a triangulated category with A…
The bounded derived category of a poset
Kosmas Diveris, Marju Purin, Peter Webb
We introduce a new combinatorial condition on a subinterval of a poset P (a clamped subinterval) that allows us to relate the Auslander-Reiten quiver of the bounded derived categor…
On the projective dimensions of Mackey functors
S. Bouc, R. Stancu, P. J. Webb
We examine the projective dimensions of Mackey functors and cohomological Mackey functors. We show over a field of characteristic that cohomological Mackey functors are Gorenst…
Combinatorial Restrictions on the Tree Class of the Auslander-Reiten Quiver of a Triangulated Category
Kosmas Diveris, Marju Purin, Peter Webb
We show that if a connected, Hom-finite, Krull-Schmidt triangulated category has an Auslander-Reiten quiver component with Dynkin tree class then the category has Auslander-Reiten…
