✦ Synopsis

We investigate the values of t(n), the maximum number of edges in a graph with n vertices and not containing a four-cycle. Techniques for finding these are developed and the values of t(n) for all n up to 21 are obtained. All the corresponding extremal graphs are found.

## Abstract We derive bounds for __f(v)__, the maximum number of edges in a graph on __v__ vertices that contains neither three‐cycles nor four‐cycles. Also, we give the exact value of __f(v)__ for all __v__ up to 24 and constructive lower bounds for all __v__ up to 200. © 1993 John Wiley & Sons, I

It is shown that there is a constant \(c\) such that if \(G\) is a graph embedded in a surface of genus \(g\) (either orientable or non-orientable) and the length of a shortest non-bounding cycle of \(G\) is at least \(c \log (g+1)\), then \(G\) is six-colorable.

It is easy to see that planar graphs without 3-cycles are 3-degenerate. Recently, it was proved that planar graphs without 5-cycles are also 3-degenerate. In this paper it is shown, more surprisingly, that the same holds for planar graphs without 6-cycles.
