The k-distance chromatic number of trees and cycles
For any positive integer k, a k-distance coloring of a graph G is a vertex coloring of G in which no two vertices at distance less than or equal to k receive the same color. The k-distance chromatic number of G, denoted by χkGis the smallest integer α for which G has a k-distance α-coloring. In this...
