B-coloring of Some Bipartite Graphs
A b-coloring is a coloring of the vertices of a graph such that each color class contains a vertex that has a neighbor in all other color classes, and the b-chromatic number b(G) of a graph G is the largest integer k such that G admits a b-coloring with k colors. Here we show that every graph G of order n that is not a complete graph satisfies the inequality b(G) ≤ n+ω(G)−1 2 , where ω(G) is th...
متن کامل2-distance Coloring of Sparse Graphs
A 2-distance coloring of a graph is a coloring of the vertices such that two vertices at distance at most 2 receive distinct colors. We prove that every graph with maximum degree Δ at least 4 and maximum average degree less that 73 admits a 2-distance (Δ + 1)-coloring. This result is tight. This improves previous known results of Dolama and Sopena.
متن کاملList strong edge coloring of some classes of graphs
A strong edge coloring of a graph is a proper edge coloring in which every color class is an induced matching. The strong chromatic index of a graph is the minimum number of colors needed to obtain a strong edge coloring. In an analogous way, we can define the list version of strong edge coloring and list version of strong chromatic index. In this paper we prove that if G is a graph with maximu...
متن کاملSelective Graph Coloring in Some Special Classes of Graphs
In this paper, we consider the selective graph coloring problem. Given an integer k ≥ 1 and a graph G = (V,E) with a partition V1, . . . , Vp of V , it consists in deciding whether there exists a set V ∗ in G such that |V ∗ ∩ Vi| = 1 for all i ∈ {1, . . . , p}, and such that the graph induced by V ∗ is k-colorable. We investigate the complexity status of this problem in various classes of graphs.
متن کاملDistance-Balanced Closure of Some Graphs
In this paper we prove that any distance-balanced graph $G$ with $Delta(G)geq |V(G)|-3$ is regular. Also we define notion of distance-balanced closure of a graph and we find distance-balanced closures of trees $T$ with $Delta(T)geq |V(T)|-3$.
