含半群生成元的解析函数的系数泛函与Bohr-Rogosinski现象

Coefficient Functional and Bohr-Rogosinski Phenomenon for Analytic functions involving Semigroup Generators

Surya Giri, S. Sivaprasad Kumar

摘要:

本文研究了一类半群生成元的系数问题,这是最近在几何函数论的背景下研究的复动力学的一个主题。进一步,得到了二阶Hankel行列式、三阶Toeplitz行列式和Hermitian-Toeplitz行列式等系数泛函的精确界.此外,给出了连续系数的锐增长估计和差界,并利用它们证明了半群生成元类的Bohr和Bohr-Rogosinski现象.

英文摘要:

This paper examines the coefficient problems for the class of semigroup generators, a topic in complex dynamics that has recently been studied in context of geometric function theory. Further, sharp bounds of coefficient functional such as second order Hankel determinant, third order Toeplitz and Hermitian-Toeplitz determinants are derived. Additionally, the sharp growth estimates and the bounds of difference of successive coefficients are determined, which are used to prove the Bohr and the Bohr-Rogosinski phenomenon for the class of semigroup generators.
