具有扰动狄利克雷积分边界条件的非线性微分方程

Nonlinear Differential Equations with Perturbed Dirichlet Integral Boundary Conditions

Alberto Cabada, Javier Iglesias

摘要:

利用参数依赖积分证明了一类二阶非齐次Dirichlet条件下的微分方程正解的存在性。所研究的问题是Dirichlet条件的一个非局部扰动,在区间的一个极端处考虑齐次Dirichlet型条件,在另一个极端处考虑积分算子。我们得到了与方程线性部分有关的格林函数的表达式,并刻画了它的常数符号。这一性质将是推导非线性问题解的存在性的基础。将不动点理论应用于定义在适当锥上的相关算子,所得结果是成立的.

英文摘要:

This paper is devoted to prove the existence of positive solutions of a second order differential equation with a nonhomogeneous Dirichlet conditions given by a parameter dependence integral. The studied problem is a nonlocal perturbation of the Dirichlet conditions by considering a homogeneous Dirichlet-type condition at one extreme of the interval and an integral operator on the other one. We obtain the expression of the Green's function related to the linear part of the equation and characterize its constant sign. Such property will be fundamental to deduce the existence of solutions of the nonlinear problem. The results hold from fixed point theory applied to related operators defined on suitable cones.
