Abstract
Let be a graph with adjacency matrix and let be a diagonal matrix of the degrees of . In 2017, Nikiforov defined the -matrix of as \begin{equation*} A_{\alpha}(G)=\alpha G)+(1-\alpha)A(G), \end{equation*}d where is an arbitrary real number. The largest eigenvalue of is called the -spectral radius of . Let , , be positive integers, satisfying , , , and (mod ). In this paper, for , we determine the extremal graphs with the maximum -spectral radius among all -connected graphs on vertices with matching number at most. This generalizes some results of O (2021) and Zhang (2022).
