چکیده
|
Introduction/purpose: the temperature of a vertex of a graph of the order n is defined as d/(n-d), where d is the vertex degree. the temperature variant of the sombor index is investigated and several of its properties established. methods: combinatorial graph theory is applied. results: extremal values and bounds for the temperature sombor index are obtained. conclusion: the paper contributes to the theory of sombor-index-like graph invariants.
