On Perverse Equivalences and Rationality
Joseph Chuang, Radha Kessar
We show that perverse equivalences between module categories of finite-dimensional algebras preserve rationality. As an application, we give a connection between some famous conjec…
Weight conjectures for fusion systems
Radha Kessar, Markus Linckelmann, Justin Lynd +1
Many of the conjectures of current interest in the representation theory of finite groups in characteristic are local-to-global statements, in that they predict consequences fo…
Blocks with normal abelian defect and abelian p' inertial quotient
David Benson, Radha Kessar, Markus Linckelmann
Let be an algebraically closed field of characteristic , and let be either or its ring of Witt vectors . Let a finite group and a block of $\…
On Picard groups of blocks of finite groups
Robert Boltje, Radha Kessar, Markus Linckelmann
We show that the subgroup of the Picard group of a -block of a finite group given by bimodules with endopermutation sources modulo the automorphism group of a source algebra is…
Rationality of blocks of quasi-simple finite groups
Niamh Farrell, Radha Kessar
Let be a prime number. We show that the Morita Frobenius number of an -block of a quasi-simple finite group is at most 4 and that the strong Frobenius number is at mos…
Local-global conjectures and blocks of simple groups
Gunter Malle, Radha Kessar
We give an expanded treatment of our lecture series at the 2017 Groups St Andrews conference in Birmingham on local-global conjectures and the block theory of finite reductive grou…
