Non-trivial steady states for wave equations and other field equations are often called solitons.
Here I will focus on so-called non-topological solitons. There are many examples of field equations admitting soliton solutions, including non-linear Klein-Gordon, Einstein-Klein-Gordon , Einstein-Yang-Mills, Yang-Mills-Higgs. In this course I will give an introduction to results on local and global existence for non-linear wave equations, discuss examples of steady states, and describe some known facts and open problems concerning the stability properties of solitons.
