The number of cliques in graphs covered by long cycles

Naidan Ji, Dong Ye

Let $G$ be a 2-connected $n$ -vertex graph and $N_{s} (G)$ be the total number of $s$ -cliques in $G$ . Let $k \geq 4$ and $s \geq 2$ be integers. In this paper, we show that if $G$ has an e…

Minimal quadrangulations of surfaces

Wenzhong Liu, M. N. Ellingham, Dong Ye

A quadrangular embedding of a graph in a surface $Σ$ , also known as a quadrangulation of $Σ$ , is a cellular embedding in which every face is bounded by a $4$ -cycle. A quadrangulati…
