摘要:

星形函数$f$的特征在于位于右半平面中的量$zf'(z)/f(z)$。本文讨论某些对称Toeplitz行列式的精确界,这些行列式的项是函数$f$的系数,对于这些函数,量$zf'(z)/f(z)$在右半平面的某些特定子集中取值。所得结果包括几个新的特殊情况和一些已知的结果。

英文摘要:

A starlike function $f$ is characterized by the quantity $zf'(z)/f(z)$ lying in the right half-plane. This paper deals with sharp bounds for certain symmetric Toeplitz determinants whose entries are the coefficients of the functions $f$ for which the quantity $zf'(z)/f(z)$ takes values in certain specific subset in the right half-plane. The results obtained include several new special cases and some known results.
