COMPUTATION OF VERTEX DEGREE ENERGY OF A GRAPH
Advances and Applications in Discrete Mathematics, 2017Summary: Using Huckel molecular orbital (HMO) theory of total \(\pi\)-electron energy, \textit{I. Gutman} [Ber. Math.-Stat. Sekt. Forschungszent. Graz 103, 22 S. (1978; Zbl 0402.05040)] conceived the idea of energy of a graph with the help of adjacency matrix. Adjacent atoms may or may not have same degree.

Distance degrees of vertex-transitive graphs
Graphs and Combinatorics, 1989In [4], a lower bound of distance degrees of distance degree regular graphs is obtained. In this paper, we prove that a lower bound will be improved in some cases of vertex-transitive graphs.

Splice graphs and their vertex-degree-based invariants
2017Summary: Let \(G_1\) and \(G_2\) be simple connected graphs with disjoint vertex sets \(V(G_1)\) and \(V(G_2)\), respectively. For given vertices \(a_1 \in V(G_1)\) and \(a_2 \in V(G_2)\), a splice of \(G_1\) and \(G_2\) by vertices \(a_1\) and \(a_2\) is defined by identifying the vertices \(a_1\) and \(a_2\) in the union of \(G_1\) and \(G_2\).

Note on vertex degrees of planar graphs
Journal of Graph Theory, 1984Let \(d_ 1,...,d_ 2\) denote the degree sequence of a graph, and let \(M_ 2=\sum^{n}_{i=1}d^ 2_ i.\) The author shows that if G is an outerplanar graph of order \(n\geq 3\) then \(M_ 2\leq n^ 2+7n-18.\) Also if G is a planar graph of order \(n\geq 4\) then \(M_ 2\leq 2n^ 2+12n-44.\) These results are proved by induction on n.
