摘要：

The variable sum exdeg index of a graph G is defined by SEl(a)(G) = Sigma ub epsilon E(G)[a(degG(u))], where a not equal 1 is a positive real number. In this paper the notion of variable sum exdeg polynomial of a connected graph is presented. The effects of this polynomial under some graph operations are computed. As an application the behaviour of some nanotubes and nanotori under this polynomial are investigated.
