具扩散的空间离散Nicholson苍蝇方程波前解的存在性

Existence of Traveling Wave Fronts for the Spatially Discrete Nicholson's Blowflies Equation with Diffusion

利用上下解方法研究了具扩散的Nicholson苍蝇方程的空间离散化模型波前解的存在性,并证明了存在具有临界波速的波前解。

It is dealed with that the existence of traveling wave fronts for the spatially discrete model of the diffusive Nichloson＇s blowflies equation. The existence of such solutions is proved using the upper-lower solution technique. It is also showed that the traveling wave front with the critical wave speed exists.
