A note on vertices of indecomposable

Linckelmann, M. (2020). A note on vertices of indecomposable. Journal of Group Theory, 23(3), pp. 385-391. doi: 10.1515/jgth-2019-0130


G. Navarro raised the question of when two vertices of two indecomposable modules over a finite group algebra generate a Sylow p-subgroup. The present note provides a sufficient criterion for this to happen. This generalises a result by Navarro for simple modules over finite p-solvable groups, which is the main motivation for this note.
