Extremal problems for disjoint graphs

Zhenyu Ni, Jing Wang, Liying Kang

For a simple graph $F$ , let $EX (n, F)$ and $E X_{sp} (n, F)$ be the set of graphs with the maximum number of edges and the set of graphs with the maximum spectral ra…

Spectral extremal graphs for edge blow-up of star forests

Jing Wang, Zhenyu Ni, Liying Kang +1

The edge blow-up of a graph $G$ , denoted by $G^{p + 1}$ , is obtained by replacing each edge of $G$ with a clique of order $p + 1$ , where the new vertices of the cliques are all distinc…
