In this thesis, we are interested in various coloring of graphs under constraints. We study acyclic coloring, strong edge coloring and adjacent vertex-distinguishing edge coloring.In Chapter 2, we consider acyclic coloring and we bound the acyclic chromatic number by a function of the maximum degree of the graph. We also study acyclic list coloring. The notion of acyclic list coloring of planar graphs was introduced by Borodin, Fon-Der Flaass, Kostochka, Raspaud, and Sopena. They conjectured that every planar graph is acyclically 5-choosable. We obtain some sufficient conditions for planar graphs to be acyclically 3-choosable.In Chapter 3, we study strong edge coloring of graphs. We prove some upper bounds of the strong chromatic index of s...
