Extremal quasi-unicyclic graphs with respect to vertex-degree function index

HIGHLIGHTS

  • who: Mathematics Subject Classification and collaborators from the Faculty of and Computer Science, University have published the paper: Extremal quasi-unicyclic graphs with respect to vertex-degree function index, in the Journal: (JOURNAL) of 26/06/2022
  • how: In this paper the vertex-degree function index Hf (G) is considered when function f (x) belongs to four classes of functions determined by the following properties strictly convex versus strictly concave and strictly increasing versus strictly decreasing.

SUMMARY

    If G is a quasi-unicyclic graph then δ(G) ≤ 3 since by deleting a . . .
