Abstract

In this paper, the existence of the nonhomogeneous steady states of a nonlocal memory model under Dirichlet boundary condition is investigated. The nonlocal kernel is assumed to be the Green’s function of a diffusion equation. By using the Crandall–Rabinowitz abstract bifurcation theory, the occurrence of a steady-state bifurcation is proved, which guarantees the existence of the nonhomogeneous steady states.

具有非局部记忆和Dirichlet边界的基于记忆的扩散模型中非齐次稳态的存在性

本文研究了一类非局部存储模型在Dirichlet边界条件下非齐次稳态的存在性。假定非局部核是扩散方程的格林函数。利用Crandall-Rabinowitz抽象分岔理论，证明了稳态分岔的存在性，从而保证了非齐次稳态的存在性。
