Abstract
Let Gbe a graph. A vertex subversion strategy of G, say S, is a set of vertices in G whose closed neighbourhood is removed from G. The survival-subgraph is denoted by G/S. The neighbour-integrity of G
NI(G), is defined to be , where S is any vertex subversion strategy of G, and c(G/S) is the maximum order of the components of G/S. This paper includes results on the neighbour-integrity of total graphs.
