The chromatic threshold of a class of graphs is the value θ such that any graph in this class with a minimum degree greater than θn has a bounded chromatic number. Several important results related to the chromatic threshold of triangle-free graphs have been reached in the last 13 years, culminating in a result by Brandt and Thomassé stating that any triangle-free graph on n vertices with minimum degree exceeding 1/3 n has chromatic number at most 4. In this paper, the researcher examines the class of triangle-free graphs that are additionally regular. The researcher finds that any triangle-free graph on n vertices that is regular of degree (1/4+a)n with a \u3e 0 has chromatic number bounded by f (a), a function of a independent of the orde...
