Bounds on Nirmala energy of graphs

Abstract

The Nirmala matrix of a graph and its energy have recently defined. In this paper, we establish some features of the Nirmala eigenvalues. Then we propose various bounds on the Nirmala spectral radius and energy. Moreover, we derive a bound on the Nirmala energy including graph energy and maximum vertex degree.

Nirmala Indices of Certain Antiviral Drugs

“…Recently, some Nirmala indices were studied, for example, in [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24].…”
