Inequalities play a fundamental role in many branches of mathematics and particularly in real analysis. By using inequalities, we can find extrema, point of inflection, and monotonic behavior of real functions. Subordination and quasisubordination are important tools used in complex analysis as an alternate of inequalities. In this article, we introduce and systematically study certain new classes of meromorphic functions using quasisubordination and Bessel function. We explore various inequalities related with the famous Fekete-Szego inequality. We also point out a number of important corollaries.

拟从属在某些亚纯函数类中的应用

不等式在数学的许多分支中，特别是在实际分析中，起着根本性的作用。通过使用不等式，我们可以找到极值，拐点和实函数的单调行为。从属和准从属是复杂分析中不等式的替代重要工具。在本文中，我们介绍并使用拟从属和贝塞尔函数系统地研究了某些新的亚纯函数类。我们探索与著名的Fekete-Szego不等式有关的各种不等式。我们还指出了许多重要的推论。
