弱非局部边值问题及其在地质中的应用

Weakly Nonlocal Boundary Value Problems with Application to Geology

D. Maroncelli, E. Collins

摘要:

在许多情况下,地下水在潜水含水层中的流动可以简化为一维Sturm-Liouville模型的形式:\begin{equation*} x''(t)+λx(t)=h(t)+\varepsilon f(x(t)),\hspace{.1in}t\in(0,π) \end{equation*}服从非局部边界条件\begin{equation*} x(0)=h_1+\varepsilonη_1(x)\text{ and } x(π)=h_2+\varepsilonη_2(x). \end{equation*}在本文中,我们研究了上述Sturm-Liouville问题的解的存在性假设下,$\varepsilon$是一个小参数。我们的方法将是分析性的,利用隐函数定理及其推广。

英文摘要:

In many cases, groundwater flow in an unconfined aquifer can be simplified to a one-dimensional Sturm-Liouville model of the form: \begin{equation*} x''(t)+λx(t)=h(t)+\varepsilon f(x(t)),\hspace{.1in}t\in(0,π) \end{equation*} subject to non-local boundary conditions \begin{equation*} x(0)=h_1+\varepsilonη_1(x)\text{ and } x(π)=h_2+\varepsilonη_2(x). \end{equation*} In this paper, we study the existence of solutions to the above Sturm-Liouville problem under the assumption that $\varepsilon$ is a small parameter. Our method will be analytical, utilizing the implicit function theorem and its generalizations.
