Zalcman猜想及其相关问题

The Zalcman conjecture and related problems

Samuel L. Krushkal

摘要:

20世纪60年代末,Lawrence Zalcman提出了一个猜想:单位圆盘上单叶函数$f(z) = z + \sum\limits_2^\infty a_n z^n$的系数满足尖锐不等式$|a_n^2 - a_{2n-1}| \le (n-1)^2$,其中只有Koebe函数的系数相等.这个引人注目的猜想意味着比伯巴赫猜想,调查了许多数学家,仍然是一个非常困难的开放问题,所有n > 3;它被证明只有在某些特殊情况下。我们提供了一个证明Zalcman的猜想的基础上的结果有关的pluissubharmonic泛函和度量的泛Teichmüller空间。作为推论,这意味着比伯巴赫猜想的一个新的证明。我们的方法也给出了其他新的尖锐估计大系数。

英文摘要:

At the end of 1960's, Lawrence Zalcman posed a conjecture that the coefficients of univalent functions $f(z) = z + \sum\limits_2^\infty a_n z^n$ on the unit disk satisfy the sharp inequality $|a_n^2 - a_{2n-1}| \le (n-1)^2$, with equality only for the Koebe function. This remarkable conjecture implies the Bieberbach conjecture, investigated by many mathematicians, and still remains a very difficult open problem for all n > 3; it was proved only in certain special cases. We provide a proof of Zalcman's conjecture based on results concerning the plurisubharmonic functionals and metrics on the universal Teichmüller space. As a corollary, this implies a new proof of the Bieberbach conjecture. Our method gives also other new sharp estimates for large coefficients.
