A spectral extremal problem on graphs with given size and matching number
Mingqing Zhai, Jie Xue, Ruifang Liu
Brualdi and Hoffman (1985) proposed the problem of determining the maximal spectral radius of graphs with given size. In this paper, we consider the Brualdi-Hoffman type problem of…

The maximum number of s-cliques in connected graphs and its application to spectral moment
Longfei Fang, Mingqing Zhai, Bing Wang
Extremal problems concerning the number of complete subgraphs have a long story in extremal graph theory. Let be the number of -cliques in a graph and $m={{r_m}\cho…
