Abstract

A graph G = (V, E) is called l-mixed p-connected if G - S - L is connected for all pairs S, L with⊆ V, L ⊆ E, and l|S| + |L| < p. This notion is a common generalisation of m-vertex-connectivity (l =1, p = m) and m-edge-connectivity (l ≥ m, p=m). We show how to use maximum adjacency orderings to find sparse certificates and removable cycles in l-mixed p-conneeted graphs in linear time.
