We revisit Wu and Zou non-standard quasi-monotonicity approach for proving existence of monotone wavefronts in monostable reaction–diffusion equations with delays. This allows to solve the problem of existence of monotone wavefronts in a neutral KPP–Fisher equation. In addition, using some new ideas proposed recently by Solar et al., we establish the uniqueness (up to a translation) of these monotone wavefronts.

非标准拟单调性:对中性KPP-Fisher方程中的波动存在性的一种应用

我们再次使用Wu和Zou非标准的拟单调性方法来证明存在时滞的单稳态反应扩散方程中的单调波阵面的存在。这可以解决中性KPP-Fisher方程中单调波前存在的问题。另外,利用Solar等人最近提出的一些新思想,我们确定了这些单调波前的唯一性(直至翻译)。
