Abstract :In this note we consider the generalization of vertex of finite groups to noncommutative rings. Let K be a field with characteristic p, and G a finite group. For an indecomposable KG-module V, a p-subgroup P of G is vertex of V if P satisfies the following conditions:(a) V is P-projective (b) For any subgroup H of G, if V is H -projective then there exist t ∈ G such that P^t ∈ H.
