چکیده
Dvo?ák and Postle introduced the concept of DP-coloring to overcome some difficulties in list coloring. Sittitrai Nakprasit combined defective coloring define a new coloring—relaxed DP-coloring. For relaxed DP-coloring, Sribunhung et al. proved that planar graphs without 4- 7-cycles are DP-(0, 2, 2)-colorable. Li 4, 8-cycles or 9-cycles DP-(1, 1, 1)-colorable. Lu Zhu 5-cycles, 6-cycles, In this paper, we show 6-cycles

Total coloring of planar graphs without some chordal 6-cycles
A k-total-coloring of a graph G is a coloring of vertex set and edge set using k colors such that no two adjacent or incident elements receive the same color. In this paper, we prove that if G is a planar graph with maximum ∆ ≥ 8 and every 6-cycle of G contains at most one chord or any chordal 6-cycles are not adjacent, then G has a (∆ + 1)-total-coloring.
متن کاملEquitable ∆-Coloring of Planar Graphs without 4-cycles
In this paper, we prove that if G is a planar graph with maximum degree ∆ ≥ 7 and without 4-cycles, then G is equitably m-colorable for any m≥ ∆.
متن کاملIncidence coloring of planar graphs without adjacent small cycles
An incidence of an undirected graph G is a pair (v, e) where v is a vertex of G and e an edge of G incident with v. Two incidences (v, e) and (w, f) are adjacent if one of the following holds: (i) v = w, (ii) e = f or (iii) vw = e or f . An incidence coloring of G assigns a color to each incidence of G in such a way that adjacent incidences get distinct colors. In 2012, Yang [15] proved that ev...
متن کاملList-Coloring the Squares of Planar Graphs without 4-Cycles and 5-Cycles
Let G be a planar graph without 4-cycles and 5-cycles and with maximum degree ∆ ≥ 32. We prove that χ`(G ) ≤ ∆ + 3. For arbitrarily large maximum degree ∆, there exist planar graphs G∆ of girth 6 with χ(G 2 ∆) = ∆ + 2. Thus, our bound is within 1 of being optimal. Further, our bound comes from coloring greedily in a good order, so the bound immediately extends to online list-coloring. In additi...
متن کاملOn 3-colorable planar graphs without short cycles
Let G be a graph. It was proved that if G is a planar graph without {4, 6, 7}-cycles and without two 5-cycles sharing exactly one edge, then G 3-colorable. We observed that the proof of this result is not correct. 1 Let G be a simple graph with vertex set G. A planar graph is one that can be drawn on a plane in such a way that there are no “edge crossings,” i.e. edges intersect only at their co...
