摘要:

该文研究Banach空间中一类非线性Volterra型微分积分方程在无穷区间R+上的耦合最小最大拟解及解的整体存在性.利用单调迭代方法及Monch不动点定理,给出了该类方程耦合最小最大拟解及解的整体存在性定理,改进、推广了[1-2]中的相应结果.

关键词: 微分积分方程, 单调迭代方法, Monch不动点定理, Kuratowski非紧性测度.

Abstract:

The existence of global solutions and coupled minimal and maximal quasisolutions are studied for a class of nonlinear integrodifferential equations on the infinite interval R+ in Banach spaces. Some existence theorems of global solutions and coupled minimal and maximal quasisolutions are obtained which improve and generalize the related results in [1-2].

Key words: Integrodifferential equations, Monotone iterative method, Monch fixed point theorem, Kuratowski noncompactness measure.
