A topological shooting method and the existence of kinks of the extended Fisher-Kolmogorov equation
For the extended Fisher-Kolmogorov equation, the authors develop a topological shooting method and apply it to prove the existence of a countably infinite number of kinks or heteroclinic orbits connecting the stable states. The discussion is made according to a critical value of the positive (constant) coefficient of the fourth order term of the equation. (When this coefficient is zero, the equation reduces to the Fisher-Kolmogorov one).
