Query: A note on vertices of indecomposable tensor products   G. Navarro raised the question under what circumstancs two vertices of two
indecomposable modules over a finite group algebra generate a Sylow
$p$-subgroup. The present note provides a sufficient criterion for when this is
the case. This generalises a result by Navarro for simple modules over finite
$p$-solvable groups, which is the main motivation for this note.
