外1-平面图的均匀边染色
Equitable Edge Coloring of Outer-1-Planar Graphs
摘要
Abstract
An s-equitable edge-k-coloringof a graph G is an edge coloring of G using k colors so that the sizes of any two color classes incident with any fixed vertex of G differ by at most s . The s-equitable edge chromatic threshold of G is the smallest k such that G has an s-equitable edge-t -colorings for integer t that is no less than k . It is proved that the 1-equitable edge chromatic threshold of any outer-1-planar graph is at most 5, the 1-equitable edge chro-matic threshold of any outer-1-planar graph without adjacent triangles is at most 4, and the 2-equitable edge chromatic threshold of any outer-1-planar graph is exactly 1.关键词
