固定第二系数函数的微分从属在几何函数论中的应用

Applications of differential subordination for functions with fixed second coefficient to geometric function theory

Lee See Keong, V. Ravichandran, Shamani Supramaniam

摘要:

Miller和Mocanu发展的一阶微分从属理论最近被R. M. Ali,S. Nagpal和V. Ravichandran [具有固定初始系数的解析函数的二阶微分从属,Bull. Malays。数学科学Soc.(2)34(2011),611- 629],并应用于获得几何函数论中经典结果的几个推广。本文给出了这一从属理论的进一步应用。特别地,给出了规范化解析函数的星形、凸性、近凸性的几个充分条件。与以前已知的结果的连接被指出。

英文摘要:

The theory of first-order differential subordination developed by Miller and Mocanu was recently extended to functions with fixed initial coefficient by R. M. Ali, S. Nagpal and V. Ravichandran [Second-order differential subordination for analytic functions with fixed initial coefficient, Bull. Malays. Math. Sci. Soc. (2) 34 (2011), 611--629] and applied to obtain several generalization of classical results in geometric function theory. In this paper, further applications of this subordination theory is given. In particular, several sufficient conditions related to starlikeness, convexity, close-to-convexity of normalized analytic functions are derived. Connections with previously known results are pointed out.
