The tangent is defined as the single point where a straight line meets a curved surface. The tangent can be determined with a collection of mathematical formulas but is most commonly determined by ...
The inverse degree of a graph G with no isolated vertices is defined as the sum of reciprocal of vertex degrees of the graph G. In this paper, we obtain several lower and upper bounds on inverse ...
Abstract.In this paper, we determine the degree distance of G× K r 0 , r 1 ,..., r n−1 and G⊠K r 0 , r 1 ,..., r n−1 , where × and ⊠denote the tensor product and strong product of graphs, ...
