我们给出了一个新的、简单的证明,证明了最近由林振生和王振来发现的一个事实:环面的格林函数有三个或五个临界点,这取决于环面的模数。该证明使用了反全纯动力学。作为副产品,我们发现了一族单参数反全纯动力系统,其参数空间仅由双曲分量和分隔它们的解析曲线组成。
We give a new, simple proof of the fact recently discovered by C.-S. Lin and C.-L. Wang that the Green function of a torus has either three or five critical points, depending on the modulus of the torus. The proof uses anti-holomorphic dynamics. As a byproduct we find a one-parametric family of anti-holomorphic dynamical systems for which the parameter space consists only of hyperbolic components and analytic curves separating them.
