摘要
利用锥与半序理论,研究Banach空间不具有单调性和紧性条件的二元算子的不动点,得出了新的不动点定理,是某些已有结果的本质改进和推广。
By using the cone and partial ordering theory, it is studied that fixed point theorems without monotone and compactness conditions in Banach spaces.And some new fixed point theorems are obtained. The results presented here are the essential improvement for some corresponding results.
