The forgotten topological index of a graph G is defined as the sum cube degrees its vertices. In this paper we establish eccentric complement line graphs and it denoted by . These are (v).e(v), where (edge vertex degree) some upper lower bounds for them.
Let G be a simple connected graph with n vertices and m edges and let d(e1) > d(e2) > · · · > d(em) be edge degree sequence of graph G. Denote by EF = ∑m i=1 d(ei) 3 reformulated forgotten index of G. Lower and upper bounds for the invariant EF are obtained.

Topological indices are a type of mathematical measure that relate to the atomic composition any straight forward finite graph. For quantitative structure-activity relationship (QSAR) and structure-property (QSPR) analyses [1]. The main aim this paper is find new bounds jump graph using some topological like Hyper Zagreb index, Nirmala Index, VL Index Forgotten index.The techniques used mathema...

In this paper, we extend the recently introduced vertex-degree-based topological index, Sombor and call it general index. The index generalizes both forgotten We present bounds in terms of other important graph parameters for also explore Nordhaus–Gaddum-type result further relations between generalized indices: Randić sum-connectivity
Introduction/purpose: The Sombor matrix is a vertex-degree-based associated with the index. paper concerned spectral properties of matrix. Results: Equalities and inequalities for eigenvalues are obtained, from which two fundamental bounds energy (= matrix) established. These depend on index "forgotten" topological Conclusion: results contribute to theory matrix, as well general matrices graph ...
