Splendid Morita equivalences for principal blocks with semidihedral defect groups
Shigeo Koshitani, Caroline Lassueur, Benjamin Sambale
We classify principal blocks of finite groups with semidihedral defect groups up to splendid Morita equivalence. This completes the classification of all principal -blocks of ta…

Trivial source endo-trivial modules for finite groups with a semi-dihedral Sylow -subgroup
Shigeo Koshitani, Caroline Lassueur
We finish off the classification of the endo-trivial modules of finite groups with Sylow -subgroups isomorphic to a semi-dihedral -group started by Carlson, Mazza and Thévena…

Trivial source characters in blocks with cyclic defect groups
Shigeo Koshitani, Caroline Lassueur
We describe the ordinary characters of trivial source modules lying in blocks with cyclic defect groups relying on their recent classification in terms of paths on the Brauer tree…
