A Lower Bound for the Number of Edges in a Graph Containing No Two Cycles of the Same Length

Chunhui Lai

In 1975, P. Erdös proposed the problem of determining the maximum number $f (n)$ of edges in a graph of $n$ vertices in which any two cycles are of different lengths. In this paper,…

The smallest degree sum that yields potentially $C_{k}$ -graphical sequence

Chunhui Lai

In this paper we consider a variation of the classical Turán-type extremal problems. Let $S$ be an $n$ -term graphical sequence, and $σ (S)$ be the sum of the terms in $S$ . Let $H$ b…
