Tripartite Zarankiewicz numbers and norm graphs

Yantao Tang, Yi Zhao

For fixed integers $s \geq t \geq 2$ , let $ex (n, n, n, K_{s, t})$ denote the maximum number of edges in a tripartite $K_{s, t}$ -free graph with $n$ vertices in each part. When…

Number of independent transversals in multipartite graphs

Yantao Tang, Yi Zhao

An independent transversal in a multipartite graph is an independent set that intersects each part in exactly one vertex. We show that for every even integer $r \geq 2$ , there exist…
