International Journal of Mathematics and Mathematical Sciences, 1983, vol. 6, 1-5

Abstract:

Gyárfás has recently constructed an elegant new example of a triangle-free infinite graph G with infinite chromatic number. We analyze its structure by studying the properties of a nested family of subgraphs G n whose union is G .
