Abstract

Results in diverse areas, such as the Nielsen‐Schreier theorem on subgroups of free groups and a proof of A. T. White's conjecture on the genus of subgroups are shown to be immediate consequences of a lemma which has already proved useful in investigating topological properties and automorphism group of graphs.

In [15] , Thomassen proved that any triangle-free k-connected graph has a contractible edge. Starting with this result, there are several results concerning the existence of contractible elements in k-connected graphs which do not contain specified subgraphs. These results extend

We define the (elementary) binary contraction Gs of a graph G = (V, E) in the following way: if (S) is an induced K,,, not contained into an induced Klv3, then Gs is either the induced subgraph (V\ S), or the graph obtained from (V\S) by adding a new vertex adjacent to those x E V\S such that (S U(x
