It is important to understand the dynamical behavior for the traveling wave solutions governed by singular traveling wave equations.
It had been found that some nonlinear wave equations have a one-loop soliton solution. What is the dynamical behavior of the so called one-loop soliton solution? To answer this question, traveling wave solutions for four nonlinear wave equations are discussed. Explicit parametric representations of some special traveling wave solutions are given. Our conclusion to the question is that the loop solution consists of three different breaking traveling wave solutions, and hence the so called "loop soliton solution" is actually not a real soliton solution.
