On symmetric quotients of symmetric algebras
Radha Kessar, Shigeo Koshitani, Markus Linckelmann
We investigate symmetric quotient algebras of symmetric algebras, with an emphasis on finite group algebras over a complete discrete valuation ring . Using elementary…

The inductive Alperin-McKay and blockwise Alperin weight conditions for blocks with cyclic defect groups
Shigeo Koshitani, Britta Spaeth
We verify the inductive blockwise Alperin weight (BAW) and the inductive Alperin-McKay (AM) conditions introduced by the second author for blocks of finite quasisimple groups with…

Clifford theory of characters in induced blocks
Shigeo Koshitani, Britta Spaeth
We present a new criterion to predict if a character of a finite group extends. Let be a finite group and a prime. For , we consider -blocks and of …
