Abstract :

In this paper, some exact expressions for the first reverse Zagreb alpha index, first reverse Zagreb beta index and second reverse Zagreb index of corona product of two simple graphs are determined. Using this results we obtained these indices for $t-$thorny graph and bottleneck graph.

Keywords :

Reverse Zagreb index, Corona product, $t-$thorny graph, bottleneck graph.
