In this series, we investigate the conditions under which both a graph G and its complement G¯ possess certain specified properties. We now characterize all the graphs G such that both G and G¯ have the same girth. We also determine all G such that

We investigate the conditions under which both a graph G and its complement G¯ possess a specified property. In particular, we characterize all graphs G for which G and G¯ both (a) have connectivity one, (b) have line-connectivity one, (c) are 2-co

An envelope is equivalent to a rectangle dihedron or a doubly-covered rectangle. It is cut along a tree graph that spans the four corners of the envelope to get a planar region. We show in Theorem 1 that every region satisfies the Conway criterion an
