Dynamical analysis has revealed that,for some nonlinear wave equations,loop-and inverted loop-soliton solutions are actually visual artifacts.The so-called loop-soliton solution consists of three solutions,and is not a real solution.This paper answers the question as to whether or not nonlinear wave equations exist for which a 'real' loop-solution exists,and if so,what are the precise parametric representations of these loop traveling wave solutions.
