چکیده مقاله
The variable sum exdeg index of a graph G is defined by SEIaG =
uv∈EGadegGu+adegGu
where a = 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.
