Lower defect groups and vertices of simple modules
Akihiko Hida, Masao Kiyota
We compare lower defect groups associated with -regular classes and vertices of simple modules for a block of a finite group algebra. We show that lower defect groups are contai…

Representations of the double Burnside algebra and cohomology of the extraspecial p-group II
Akihiko Hida, Nobuaki Yagita
Let E be the extraspecial p-group of order p^3 and exponent p where p is an odd prime. We consider the mod p cohomology of summands in the stable splitting of p-completed classifyi…
