Abstract
Obravnavana so vozliščna, povezavna in skupna barvanja grafov Sierpińskijevih rešetk ▫$S_n$▫, Sierpińskijevih grafov ▫$S(n,k)$▫, grafov ▫$S^+(n,k)$▫ in grafov ▫$S^{++}(n,k)$▫. V posebnem je dokazano, da velja ▫$\chi''(S_n)$▫, ▫$\chi'(S(n,k))$▫, ▫$\chi(S^+(n,k))$▫, ▫$\chi(S^{++}(n,k))$▫, ▫$\chi'(S^+(n,k))$▫ in ▫$\chi'(S^{++}(n,k))$▫.

Vertex-colorings, edge-colorings and total-colorings of the Sierpiński gasket graphs ▫$S_n$▫, the Sierpiński graphs ▫$S(n,k)$▫, graphs ▫$S^+(n,k)$▫, and graphs ▫$S^{++}(n,k)$▫ are considered. In particular ▫$\chi''(S_n)$▫, ▫$\chi'(S(n,k))$▫, ▫$\chi(S^+(n,k))$▫, ▫$\chi(S^{++}(n,k))$▫, ▫$\chi'(S^+(n,k))$▫ and ▫$\chi'(S^{++}(n,k))$▫ are determined. |
