Infinite Singular Point of Traveling Wave System of Huxley Equation

As a special nerve model,Huxley equation has important research value.The infinite singular point of traveling wave system of Huxley equation is a higher order singular point in the case of undetermined signs, whose handling situation was not simple enough in the past.A new method was proposed in this paper to find the qualitative structure of infinite singular point of such traveling wave system in a concise way.This method can also be used for some other systems.
