Abstract

ABSTRACT In this paper, the sharp solutions of Fekete-Szegö problems are provided for class of quasi-convex mappings f 1 of type B and class of quasi-convex mappings f 2 of type B and order α defined on the unit ball in a complex Banach space, respectively, where x = 0 is a zero of order k + 1 of f i ( x ) − x ( i = 1, 2). Compare with some recent works, our main theorems hold without additional restrictive conditions. Also, the proof of our main theorems are more simple than those given in the previous results.

复Banach空间中单位球上B型拟凸映射的系数问题

文摘本文Fekete-Szego问题的尖锐的解决方案提供了一类拟凸映射f 1 B型和类拟凸映射f 2 B型和秩序的α单位球上定义在一个复杂的巴拿赫空间,分别在x = 0是一个零阶k + 1 f (x)−x (i = 1, 2)。与最近的一些工作,我们的主要定理没有额外的限制条件。此外，我们的主要定理的证明比前面的结果更简单。

期刊介绍： Mathematica Slovaca, the oldest and best mathematical journal in Slovakia, was founded in 1951 at the Mathematical Institute of the Slovak Academy of Science, Bratislava. It covers practically all mathematical areas. As a respectful international mathematical journal, it publishes only highly nontrivial original articles with complete proofs by assuring a high quality reviewing process. Its reputation was approved by many outstanding mathematicians who already contributed to Math. Slovaca. It makes bridges among mathematics, physics, soft computing, cryptography, biology, economy, measuring, etc.　 The Journal publishes original articles with complete proofs. Besides short notes the journal publishes also surveys as well as some issues are focusing on a theme of current interest.
