论文摘要
In this work we analyze the behavior of the solutions to nonlocal evolution equations of the form $u_t(x,t) = \int J(x-y) u(y,t) \, dy - h_ε(x) u(x,t) + f(x,u(x,t))$ with $x$ in a perturbed domain $Ω^ε\subset Ω$ which is thought as a fixed set $Ω$ from where we remove子集$ a^ε$称为孔。我们在l^\ infty $中选择了一个适当的功能家庭$h_ε\，以便在漏洞中处理neumann和dirichlet条件。此外，我们将$ j $作为非偏见的内核和$ f $作为非本地非线性。在假设$ω^ε$的特征函数的假设下，我们研究了提供非局部均质方程的溶液的极限。
In this work we analyze the behavior of the solutions to nonlocal evolution equations of the form $u_t(x,t) = \int J(x-y) u(y,t) \, dy - h_ε(x) u(x,t) + f(x,u(x,t))$ with $x$ in a perturbed domain $Ω^ε\subset Ω$ which is thought as a fixed set $Ω$ from where we remove a subset $A^ε$ called the holes. We choose an appropriated families of functions $h_ε\in L^\infty$ in order to deal with both Neumann and Dirichlet conditions in the holes setting a Dirichlet condition outside $Ω$. Moreover, we take $J$ as a non-singular kernel and $f$ as a nonlocal nonlinearity. % Under the assumption that the characteristic functions of $Ω^ε$ have a weak limit, we study the limit of the solutions providing a nonlocal homogenized equation.
