Abstract

Linckelmann associated an invariant to a cyclic $p$-block of a finite group, which is an indecomposable endo-permutation module over a defect group, and which, together with the Brauer tree of the block, essentially determines its source algebra equivalence class. In Parts II-IV of our series of papers, we classify, for odd~$p$, those endo-permutation modules of cyclic $p$-groups arising from $p$-blocks of quasisimple groups. In the present Part II, we reduce the desired classification for the quasisimple classical groups of Lie type $B$, $C$, and $D$ to the corresponding classification for the general linear and unitary groups, which is also accomplished.
