Özet

The reverse vertex degree of a vertex v of a simple connected graph G defined as c(v) = Delta - d(v) + 1, where Delta denotes the largest of all degrees of vertices of G and d(v) denotes the number of edges incident to v. The first reverse Zagreb beta index of a simple connected graph G defined as CM1 beta(G) = Sigma(uv is an element of E(G))(c(u) + c(v)). In this paper, we characterized maximum chemical trees with respect to the first reverse Zagreb beta index.
