Maxima of the $Q$-index: Graphs with no $K_{1,t}$-minor

Combinatorics 2022-02-22 v1

Abstract

A graph is said to be \textit{HH-minor free} if it does not contain HH as a minor. In this paper, we characteristic the unique extremal graph with maximal QQ-index among all nn-vertex K1,tK_{1,t}-minor free graphs (t3t\ge3).
