Let T be a spanning tree of a connected graph G. Denote by (G; T ) the number of components in G\E(T ) with odd number of edges. The value minT (G; T ) is known as the Betti deΓΏciency of G, denoted by (G), where the minimum is taken over all spanning trees T of G. It is known (N.H. Xuong, J. Combin.

## Abstract In this article we give examples of a triangleβfree graph on 22 vertices with chromatic number 5 and a __K__~4~βfree graph on 11 vertices with chromatic number 5. We very briefly describe the computer searches demonstrating that these are the smallest possible such graphs. All 5βcritica

## Abstract Rosenfeld (1971) proved that the Total Colouring Conjecture holds for balanced complete __r__βpartite graphs. Bermond (1974) determined the exact total chromatic number of every balanced complete __r__βpartite graph. Rosenfeld's result had been generalized recently to complete __r__βpar
In this paper, we shall first prove that for a Halin graph G, 4 Β°xT (G) Β°6, where x T (G) is the vertex-face total chromatic number of G. Second, we shall establish a sufficient condition for a Halin graph to have a vertex-face total chromatic number of 6. Finally, we shall give a necessary and suff
