Abstract We initiate a study of the Euclidean distance degree in context sparse polynomials. Specifically, we consider hypersurface $$f=0$$ f = 0 defined by polynomial f that is general given its support, such support contains origin. show equals mixed ...

In $1994,$ degree distance  of a graph was introduced by Dobrynin, Kochetova and Gutman. And Gutman proposed the Gutman index of a graph in $1994.$ In this paper, we introduce the concepts of  multiplicative version of degree distance and the multiplicative version of Gutman index of a graph. We find the sharp upper bound for the  multiplicative version of degree distance and multiplicative ver...

Let G be a finite connected graph. The degree distance D′(G) of G is defined as ∑ {u,v}⊆V (G)(deg u + deg v) dG(u, v), where degw is the degree of vertex w and dG(u, v) denotes the distance between u and v in G. In this paper, we give asymptotically sharp upper bounds on the degree distance in terms of order and edge-connectivity.

Professor Frank Harary has had a singular influence on graph theory through his own extensive original research, through the training of several researchers who themselves have made many important contributions, and through popularizing work, most significantly his text Graph Theory [1]. Frank Harary has contributed to a number of more advanced specialized texts, like that of Buckley and Harary...
