Abstract

In this article we investigate the structure of uniformly kk-connected and uniformly kk-edge-connected graphs. Whereas both types have previously been studied independent of each other, we analyze relations between these two classes. We prove that any uniformly kk-connected graph is also uniformly kk-edge-connected for k3k\le 3 and demonstrate that this is not the case for k>3k>3. Furthermore, uniformly kk-connected and uniformly kk-edge-connected graphs are well understood for k2k\le 2 and it is known how to construct uniformly 33-edge-connected graphs. We contribute here a constructive characterization of uniformly 33-connected graphs that is inspired by Tuttes Wheel Theorem. Eventually, these results help us to prove a tight bound on the number of vertices of minimum degree in uniformly 33-connected graphs.
