一类混合单调算子不动点的存在惟一性

The Existence and Uniqueness of Fixed Points for a Class of Mixed Monotone Operators

在不具有任何紧性,连续性和凹凸性的条件下,对一类混合单调算子不动点的存在惟一性加以研究,得到几个新的结果。所得的部分结果推广了最近一些文献的结果。

Without any compactness or continuity or concavity（convexity） for a class of mixed monotone operators,the existence and uniqueness of their fixed points are obtained and part of the results generalizes some results in reccnt relative research worus.
