WebAn injective k-edge-coloring of a graph G is an assignment of colors, i.e. integers in f1;:::;kg, to ... Moreover all subcubic planar bipartite graphs are injectively 4-edge-colorable [14]. Note that in [1], this notion is studied as the inducde star arboricity of a graph, that is, the smallest WebAbstract A k -injective edge coloring of a graph G is a coloring f: E ( G) → C = { 1, 2, 3, …, k }, such that if e 1, e 2 and e 3 are consecutive edges in G, then f ( e 1) ≠ f ( e 3). χ i ′ ( G) = …

Injective edge-coloring of graphs with given maximum degree

WebAn injective edge-coloring c of a graph G is an edge-coloring such that if e 1, e 2, and e 3 are three consecutive edges in G (they are consecutive if they form a path or a cycle of … linear llc products

WebOct 1, 2024 · Injective edge-coloring of graphs with given maximum degree Alexandr Kostochka, André Raspaud, Jingwei Xu A coloring of edges of a graph G is injective if for any two distinct edges e_1 and e_2, the colors of e_1 and e_2 are distinct if they are at distance 1 in G or in a common triangle. WebAn injective edge coloring of a graph G = (V, E) is a coloring c of the edges of G such that if e 1, e 2 and e 3 are consecutive edges in G, then c (e 1) ≠ c (e 3 ). The injective edge coloring number χ i (G) is the minimum number of colors permitted in such a coloring. WebAn injective k -edge coloring of a graph G = ( V ( G), E ( G)) is a k -edge coloring φ such that if e 1 and e 2 are at distance exactly 2 or in the same triangle, then φ ( e 1) ≠ φ ( e 2). The injective chromatic index of G, denoted by χ i ′ ( G), is the minimum k such that G has an injective k -edge coloring. The edge weight of G is ... linearlist t
