论文摘要

令$ \ MATHCAL {S} $表示分析和单价({\ it i.e。},一对一个)函数$ f(z)= z+s+sum_ {n = 2}^{\ infty} a_n z^n $在单位disk $ \ mathbb中\ Mathbb {C}:| z | <1 \} $。对于$ f \ in \ nathcal {s} $,ma提出了广义的zalcman猜想,即$$ | a_ | a_ {n} a_ {m} -a_ {n+m-1} | \ le(n-1)(n-1)(m-1)(m-1),\,\,\,\,\,\,\,\,\,\,\,\,\ ge2 n \ ge2 n \ ge2 n \ ge2,\, $ k(z)= z/(1 -z)^2 $及其旋转。在本文中,使用Holomorphic Motion的特性和Krushkal的手术引理\ Cite {Krushkal-1995},当$ n = 2 $,$ m = 3 $和$ n = 2 $,$ m = 4 $时,我们证明了广义的Zalcman猜想。

Let $\mathcal{S}$ denote the class of analytic and univalent ({\it i.e.}, one-to-one) functions $f(z)= z+\sum_{n=2}^{\infty}a_n z^n$ in the unit disk $\mathbb{D}=\{z\in \mathbb{C}:|z|<1\}$. For $f\in \mathcal{S}$, Ma proposed the generalized Zalcman conjecture that $$|a_{n}a_{m}-a_{n+m-1}|\le (n-1)(m-1),\,\,\,\mbox{ for } n\ge2,\, m\ge 2,$$ with equality only for the Koebe function $k(z) = z/(1 - z)^2$ and its rotations. In this paper using the properties of holomorphic motion and Krushkal's Surgery Lemma \cite{Krushkal-1995}, we prove the generalized Zalcman conjecture when $n=2$, $m=3$ and $n=2$, $m=4$.
