On the first Zagreb index of graphs with Self-Loops

On the first Zagreb index of graphs with Self-Loops

AbstractSome of the most comprehensively studied degree-based topological indices are the Zagreb indices. The first Zagreb index [Formula: see text] of a graph G is defined as the sum of squares of the degrees of the vertices. Let [Formula: see text] and let [Formula: see text] be the graph obtained...
