The purpose of the present paper is to introduce several new classes of meromorphic functions defined by using a meromorphic analogue of the Choi–Saigo–Srivastava operator for analytic functions and investigate various inclusion properties of these classes. Some interesting applications involving these and other classes of integral operators are also considered. 相似文献

In the present paper, we introduce and investigate a certain subclass of meromorphic close-to-convex functions. Such results as coefficient inequalities, convolution property, distortion property and radius of meromorphic convexity are derived. 相似文献

In the present paper, we introduce a new general integral operator of meromorphic multivalent functions. The starlikeness of this integral operator is determined. Several special cases are also discussed in the form of corollaries. 相似文献

We mainly study the uniqueness of meromorphic functions sharing three distinct values CM with their difference operators, and the related result confirms the conjecture of Chen and Yi. We also obtain a uniqueness theorem on entire functions sharing two sets CM with their difference operators. 相似文献

In this article, we investigate the uniqueness problems of difference polynomials of meromorphic functions and obtain some results which can be viewed as discrete analogues of the results given by Shibazaki. Some examples are given to show the results in this article are best possible. 相似文献

Uniqueness of meromorphic functions concerning sharing two small functions with their derivatives 下载免费PDF全文
In this paper, we study the uniqueness of meromorphic functions that share two small functions with their derivatives. We prove the following result: Let $f$ be a nonconstant meromorphic function such that $\mathop {\overline{\lim}}\limits_{r\to\infty} \frac{\bar{N}(r,f)}{T(r,f)}<\frac{3}{128}$, and let $a$, $b$ be two distinct small functions of $f$ with $a\not\equiv\infty$ and $b\not\equiv\infty$. If $f$ and $f""$ share $a$ and $b$ IM, then $f\equiv f""$. 相似文献
