Abstract
- For a set of nonnegative integers c 1 , ... , c k , a (c 1 , c 2 , ... , c k) -coloring of a graph G is a partition of V (G) into V 1 , ... , V k such that for every i , 1 ≤ i ≤ k , G [ V i ] has maximum degree at most c i. In this paper, we prove that all planar graphs without 4-cycles and intersecting triangles are (1 , 1 , 0) -colorable. [ABSTRACT FROM AUTHOR]
