چکیده
|
In this paper, for every kdegree distance we define ψk-polynomial of a connected graph g=(v,e) as where ψk(i,j) is the number of edges uv in g such that {dk(v), dk(u)}={i,j} and dk(v), dk(u) are the kth degree distance of v and u, and δk, ∆k are the minimum and maximum kth distance degrees respectively. we compute the ψ2-polynomial of some standard graphs and some graph operations. also ψ2-polynomial for honeycomb network and graphene are obtained with their plotting in 3d.
