Even cycles in dense graphs

Neal Bushaw, Andrzej Czygrinow, Jangwon Yie

We will show that for $α > 0$ there is $n_{0}$ such that if $G$ is a graph on $n \geq n_{0}$ vertices such that $α n < δ (G) < (n - 1) /2$ , then for every $n_{1} + n_{2} + \dots + n_{l} = δ (G)$ , $G$ contai…

Optimal pebbling number of graphs with given minimum degree

Andrzej Czygrinow, Glenn Hurlbert, Gyula Y. Katona +1

Consider a distribution of pebbles on a connected graph $G$ . A pebbling move removes two pebbles from a vertex and places one to an adjacent vertex. A vertex is reachable under a p…
