WebAbstract. A proper vertex coloring of a graph G is r-dynamic if for each vV (G), at least min {r,d (v)} colors appear in NG (v). In this paper we investigate r-dynamic versions of coloring, list coloring, and paintability. We prove that planar and toroidal graphs are 3-dynamically 10-colorable, and this bound is sharp for toroidal graphs. Web1 de dez. de 2024 · Abstract.
