摘要

本文的目的是引入复值凸度量空间的概念，并引入最近由Okeke[24]提出的Picard-Ishikawa混合迭代格式的一种模拟。我们利用这两个新概念近似了某些压缩条件的(公)不动点，并得到了若干推论。证明了在复值凸度量空间中，Picard-Ishikawa混合迭代格式[24]比Mann、Ishikawa和Noor[23]迭代格式收敛速度更快。最后给出了一些数值算例来验证我们的结果。

FIXED POINT THEOREMS IN COMPLEX VALUED CONVEX METRIC SPACES

Our purpose in this paper is to introduce the concept of complex valued convex metric spaces and introduce an analogue of the Picard-Ishikawa hybrid iterative scheme, recently proposed by Okeke [24] in this new setting. We approximate (common) fixed points of certain contractive conditions through these two new concepts and obtain several corollaries. We prove that the Picard-Ishikawa hybrid iterative scheme [24] converges faster than all of Mann, Ishikawa and Noor [23] iterative schemes in complex valued convex metric spaces. Also, we give some numerical examples to validate our results.
