Ordering Unicyclic Connected Graphs with Girth g ≥ 3 Having Greatest SK Indices

Ordering Unicyclic Connected Graphs with Girth g ≥ 3 Having Greatest SK Indices

For a graph, the <i>SK</i> index is equal to the half of the sum of the degrees of the vertices, the <i>SK</i><sub>1</sub> index is equal to the half of the product of the degrees of the vertices, and the <i>SK</i><sub>2</sub> index is equa...
