摘要
The first and second multiplicative Zagreb indices of a simple graph G are defined as: Pi(1)(G) = Pi(u is an element of v(G)) d(G)(u)(2) and Pi(2)(G) = Pi(uv is an element of E(G)) d(G)(U)d(G)(V), where d(G)(u) denotes the degree of the vertex u of G. In this paper, we present some strict lower bounds on the first and second multiplicative Zagreb indices of several graph operations in terms of the first and second multiplicative Zagreb indices and multiplicative sum Zagreb index of their components.
