Edge-disjoint Hamilton cycles under a bipartite-hole condition

Yanan Hu, Chengli Li, Feng Liu

In 2017, McDiarmid and Yolov introduced the bipartite-hole-number $I^\pm (G)$ and proved that $I^´ (G) \geq I^\pm (G)$ forces a Hamilton cycle. They also gave a sufficient…

Longest cycles and longest chordless cycles in $2$ -connected graphs

Yanan Hu, Chengli Li, Feng Liu

Thomassen's chord conjecture from 1976 states that every longest cycle in a $3$ -connected graph has a chord. The circumference $c (G)$ and induced circumference $c^{'} (G)$ of a graph $…
