The generating hypothesis for the stable module category of a -group
David J. Benson, Sunil K. Chebolu, J. Daniel Christensen +1
Freyd's generating hypothesis, interpreted in the stable module category of a finite p-group G, is the statement that a map between finite-dimensional kG-modules factors through a…
Groups which do not admit ghosts
Sunil K. Chebolu, J. Daniel Christensen, Jan Minac
A ghost in the stable module category of a group G is a map between representations of G that is invisible to Tate cohomology. We show that the only non-trivial finite p-groups who…
Ghosts in modular representation theory
Sunil K. Chebolu, J. Daniel Christensen, Jan Minac
A ghost over a finite p-group G is a map between modular representations of G which is invisible in Tate cohomology. Motivated by the failure of the generating hypothesis---the sta…
