A note on potentially $K_{4} - e$ graphical sequences

Chunhui Lai

A sequence $S$ is potentially $K_{4} - e$ graphical if it has a realization containing a $K_{4} - e$ as a subgraph. Let $σ (K_{4} - e, n)$ denote the smallest degree sum such that every $n$ -ter…

Graphs without repeated cycle lengths

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,…
