### Abstract

Let *k* be a positive integer. A graph *G* = (*V*, *E*) is said to be Π*k*-connected if for any given subset *S* of *V*(*G*) with |*S*| = *k*, the subgraph induced by *S* is connected. In this paper, we consider Π* _{k}*–connected graphs under different graph valued functions. Π

*–connectivity of Cartesian product, normal product, join and corona of two graphs have been obtained in this paper.*
