Title:  Coloring graphs with locally few colors. (In English)
Source:  Discrete Math. 59, 21-34 (1986).
Review:  Authors' abstract: "Let G be a graph, m > r \geq 1 integers. Suppose that it has a good coloring with m colors which uses at most r colors in the neighborhood of every vertex. We investigate these so-called local r- colorings. One of our results (Theorem 2.4) states: The chromatic number of G, Chr(G) \leq r2r log2 log2 m and this value is the best possible in a certain sense. We consider infinite graphs as well."
