Colorings with Fractional Defect

Combinatorics 2019-11-11 v2

Abstract

Consider a coloring of a graph such that each vertex is assigned a fraction of each color, with the total amount of colors at each vertex summing to 11. We define the fractional defect of a vertex vv to be the sum of the overlaps with each neighbor of vv, and the fractional defect of the graph to be the maximum of the defects over all vertices. Note that this coincides with the usual definition of defect if every vertex is monochromatic. We provide results on the minimum fractional defect of 22-colorings of some graphs.
