摘要

本文主要研究具有时空记忆和迪里夏特边界条件的反应扩散方程。我们通过局部和全局分岔理论证明了正稳态解的存在，并提供了正稳态解的稳定性条件。我们的一般结果被应用于具有时空记忆的扩散对数模型。

Existence and stability of steady states of reaction–diffusion equation with spatiotemporal memory

This paper focuses on a reaction–diffusion equation with spatiotemporal memory and Dirichlet boundary condition. We prove the existence of positive steady-state solutions through local and global bifurcation theory and provide the conditions for the stability of positive steady-state solutions. Our general results are applied to a diffusive logistic population model with spatiotemporal memory.
