首发时间:2006-07-20
摘要:在本文中,我们讨论了区域R^N中的非局部椭圆方程解的存在性,首先利用迦疗金方法得到了有界区域中的没有非局部项 的椭圆方程解的存在性,然后利用上下解方法得到了全空间R^N中的没有非局部项 的椭圆方程解的存在性,最后通过一个代数方程得到了原问题解的存在性.

The Existence of Solutions to The Nonlocal Elliptic equation in An Unbounded Domain R^N
Abstract:In this paper, we study the existence of solutions for the nonlocal elliptic equation in R^N. By Galerkin method, we first get the existence of solutions for the elliptic equation without nonlocal term in a bounded domain ,then by sub-super solution method,the existence of solutions for the elliptic equation without nonlocal term in R^N is discussed, at last, by an algebraic method we get the existence of solutions to the problem.
Keywords: nonlocal equation, Galerkin method, sub-super solution method.
