一个正不动点定理及其对Hammerstein积分方程组的应用

A positive fixed point theorem with applications to systems of Hammerstein integral equations

Alberto Cabada, José Ángel Cid, Gennaro Infante

摘要:

结合单调性假设和经典的不动点指数理论,给出了不动点存在的新判据。作为一个说明性的应用,我们用我们的理论结果证明了非线性Hammerstein积分方程组正解的存在性。最后给出了一个例子来说明我们的结果的适用性。

英文摘要:

We present new criteria on the existence of fixed points that combine some monotonicity assumptions with the classical fixed point index theory. As an illustrative application, we use our theoretical results to prove the existence of positive solutions for systems of nonlinear Hammerstein integral equations. An example is also presented to show the applicability of our results.
