不具有空间平移不变性的单调演化系统的传播动力学

Propagation Dynamics for Monotone Evolution Systems without Spatial Translation Invariance

Taishan Yi, Xiao-Qiang Zhao

摘要:

本文在一个抽象的背景下,建立了一类不具有空间平移不变性的单调发展系统的空间非齐次平衡态的存在性和渐近传播性质.然后,我们应用发展的理论研究行波和时空传播模式的时滞非局部方程,反应扩散方程在一个圆柱,渐近齐次KPP型方程。我们还得到了一类具Dirichlet边界条件的时滞反应扩散方程的稳态解的存在性和解的渐近扩散性质.

英文摘要:

In this paper,under an abstract setting we establish the existence of spatially inhomogeneous steady states and the asymptotic propagation properties for a large class of monotone evolution systems without spatial translation invariance. Then we apply the developed theory to study traveling waves and spatio-temporal propagation patterns for time-delayed nonlocal equations, reaction-diffusion equations in a cylinder, and asymptotically homogeneous KPP-type equations. We also obtain the existence of steady state solutions and asymptotic spreading properties of solutions for a time-delayed reaction-diffusion equation subject to the Dirichlet boundary condition.
