[In this chapter, we study vertex colorings of graphs, where the colors are elements of ℤk\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathbb{Z}_{k}$$ \end{document} or of [k] for some integer k ≥ 2. These give rise to either edge-distinguishing labelings or proper edge colorings defined in a variety of ways.]
