讨论了一类混合单调算子的耦合不动点定理,并获得了最大最小耦合不动点.作为应用,讨论了Banach空间中含有不连续项的混合单调Volterra型积分方程耦合拟解的存在性问题.
We discuss coupled fixed point theorems for a class of mxied monotone operators and obtain coupled minimal-maximal fixed points. As an applicaton, the existence problems of coupled quasi-solutions for mixed monotone Volterra integral equations with discontinuous terms in Banach space are discassed .
