On degree power sum in $P_{k}$ -free graphs

Jiangdong Ai, Fankang He, Yihang Liu +1

Let $G$ be a graph on $n$ vertices with degree sequence $(d_{1}, d_{2} ...... d_{n})$ . For a real $p \geq 1$ , let $D_{p} (G) = \sum_{i = 1}^{n} d_{i}^{p}$ . A Turán-type problem of degree power sum was in…

Solution on strong partition of $2$ -balanced regular multipartite tournaments

Jiangdong Ai, Fankang He, Yihang Liu

We call a partition of a $c$ -partite tournament into tournaments of order $c$ is strong if each tournament is strongly connected. The strong partition number denoted as $S T (r)$ , re…
