利用新的不动点定理证明$n^\mathrm{th}$阶非线性微分边值问题解的存在性

Existence of solutions for $n^\mathrm{th}$-order nonlinear differential boundary value problems by means of new fixed point theorems

Alberto Cabada, Lorena Saavedra

摘要:

本文证明了一类非线性微分边值问题的一个或多个解的存在性。为此,我们得到了一类积分算子的新的不动点定理。我们遵循著名的Krasnoselski \u的不动点定理和两个Leggett-Williams型的不动点结果.在得到一类单参数非线性微分方程解的存在性的一般结果后,作为特例,证明了二阶和四阶非线性边值问题解的存在性.

英文摘要:

This paper is devoted to prove the existence of one or multiple solutions of a wide range of nonlinear differential boundary value problems. To this end, we obtain some new fixed point theorems for a class of integral operators. We follow the well-known Krasnoselski\uı's fixed point Theorem together with two fixed point results of Leggett-Williams type. After obtaining a general existence result for a one parameter family of nonlinear differential equations, are proved, as particular cases, existence results for second and fourth order nonlinear boundary value problems.
