Abstract
The aim of this paper is to give an upper and lower bounds for the first and second Zagreb indices of quasi bicyclic graphs. For a simple graph , we denote and , as the sum of overall vertices in and the sum of of all edges of , respectively. The graph is called quasi bicyclic graph if there exists a vertex such that is a connected bicyclic graph. The results mentioned in this paper, are mostly new or an important of result given by authors for quasi unicyclic graphs in [1].
