摘要
在完备锥S-度量空间中,利用迭代方法,研究了一类扩张映射的不动点存在性问题.在非连续条件下,证明了几个不动点定理.所得结果推广了一些文献的相关结论,改进了相关的证明方法.
In this paper,using the iteration method,the existence of fixed points of a class of expansion mapping in complete cone S-metric space was studied.Under non-continuous conditions,several fixed point theorems were proved.The result obtained extends some related conclusions and the proof method is improved.
