摘要
根据平面动力系统的分支理论,研究了广义Fisher方程在平衡点是鞍点或结点时,讨论了它的抛物线解的存在性.由抛物线解的存在性,在不同的参数条件下,得到了方程扭波解的精确参数表示.
By finding parabola solutions of a planar dynamical systems connecting two equilibrium points, the existence of the kink wave solutions and their exact parametric representations are obtained for a Fisher Equation. Explicit parametric conditions to guarantee the existence of the above solutions are given.
