## Abstract It is consistent that for every function __f__:ω → ω there is a graph with size and chromatic number ℵ~1~ in which every __n__‐chromatic subgraph contains at least __f__(__n__) vertices (__n__ ≥ 3). This solves a $ 250 problem of Erdős. It is consistent that there is a graph __X__ with

A graph G is called k-critical if x(G) = k and x(G -e) -C x(G) for each edge e of G, where x denotes the chromatic number. T. Gallai conjectured that every k-critical graph of order n contains at most n complete (kl)-subgraphs. In 1987, Stiebitz proved Gallai's conjecture in the case k = 4, and in 1
## Abstract Rosenfeld (1971) proved that the Total Colouring Conjecture holds for balanced complete __r__‐partite graphs. Bermond (1974) determined the exact total chromatic number of every balanced complete __r__‐partite graph. Rosenfeld's result had been generalized recently to complete __r__‐par
For each pair k, rn of natural numbers there exists a natural number f(k, rn) such that every f ( k , m)-chromatic graph contains a k-connected subgraph of chromatic number at least rn.
## Abstract We show that a complete multipartite graph is class one if and only if it is not eoverfull, thus determining its chromatic index.
Xu, S., The chromatic uniqueness of complete bipartite graphs, Discrete Mathematics 94 (1991) 153-159. This paper is partitioned into two parts. In the first part we determine the maximum number of induced complete bipartite subgraphs in graphs with some given conditions. Using a theorem given in th
