Schramm-Loewner演化的数值计算

Numerical computations for the Schramm-Loewner Evolution

Tom Kennedy

摘要:

本文综述了与Schramm-Loewner演化有关的两种数值方法。第一个模拟SLE本身。更一般地说,它找到了半平面中的曲线,该曲线是由给定驱动函数的Loewner方程得出的。第二种方法可以被认为是逆问题。给定半平面中的一条简单曲线,它计算Loewner方程中的驱动函数。该算法通过计算曲线的驱动过程并检验其是否为布朗运动,从而检验半平面中给定的随机曲线族是否为SLE。更一般地说,该算法可用于计算可能不是SLE的随机曲线的驱动过程。这里介绍的大部分材料以前都出现过。我们的目标是给一个教学的审查,说明在这些计算中出现的一些实际问题,并讨论一些开放的问题。

英文摘要:

We review two numerical methods related to the Schramm-Loewner evolution (SLE). The first simulates SLE itself. More generally, it finds the curve in the half-plane that results from the Loewner equation for a given driving function. The second method can be thought of as the inverse problem. Given a simple curve in the half-plane it computes the driving function in the Loewner equation. This algorithm can be used to test if a given random family of curves in the half-plane is SLE by computing the driving process for the curves and testing if it is Brownian motion. More generally, this algorithm can be used to compute the driving process for random curves that may not be SLE. Most of the material presented here has appeared before. Our goal is to give a pedagogic review, illustrate some of the practical issues that arise in these computations and discuss some open problems.
