On automorphisms and focal subgroups of blocks
Markus Linckelmann
Given a p-block B of a finite group with defect group P and fusion system F on P we show that the rank of the group P/foc(F) is invariant under stable equivalences of Morita type.…
Block algebras with HH1 a simple Lie algebra
Markus Linckelmann, Lleonard Rubio y Degrassi
We show that if is a block of a finite group algebra over an algebraically closed field of prime characteristic such that $\HH^1(B)$ is a simple Lie algebra and su…
On Morita and derived equivalences for cohomological Mackey algebras
Markus Linckelmann, Baptiste Rognerud
By results of the second author, a source algebra equivalence between two -blocks of finite groups induces an equivalence between the categories of cohomological Mackey functors…
On Tate duality and a projective scalar property for symmetric algebras
Florian Eisele, Michael Geline, Radha Kessar +1
We identify a class of symmetric algebras over a complete discrete valuation ring of characteristic zero to which the characterisation of Knörr lattices in terms of st…
On blocks of defect two and one simple module, and Lie algebra structure of
David John Benson, Radha Kessar, Markus Linckelmann
Let be a field of odd prime characteristic . We calculate the Lie algebra structure of the first Hochschild cohomology of a class of quantum complete intersections over .…
