随机时变对Loewner壳的影响

Effect of Random Time Changes on Loewner Hulls

Kei Kobayashi, Joan Lind, Andrew Starnes

摘要:

Loewner壳由其实值驱动函数确定。我们研究的几何效应的Loewner壳时,驱动功能是由一个随机的时变,如逆的$α$稳定从属。在对比SLE,我们表明,对于一个大类的随机时变,随时间变化的布朗运动过程不会产生一个简单的曲线。此外,我们开发的标准,可以应用在许多情况下,以确定是否产生的Loewner船体随时间变化的驱动功能是简单的或非简单的。为了帮助我们分析的一个例子与时变的确定性驱动函数,我们证明了一个确定性的结果,驱动功能,移动速度比$at^r$为$r \in (0,1/2)$产生一个外壳,离开真正的切线。

英文摘要:

Loewner hulls are determined by their real-valued driving functions. We study the geometric effect on the Loewner hulls when the driving function is composed with a random time change, such as the inverse of an $α$-stable subordinator. In contrast to SLE, we show that for a large class of random time changes, the time-changed Brownian motion process does not generate a simple curve. Further we develop criteria which can be applied in many situations to determine whether the Loewner hull generated by a time-changed driving function is simple or non-simple. To aid our analysis of an example with a time-changed deterministic driving function, we prove a deterministic result that a driving function that moves faster than $at^r$ for $r \in (0,1/2)$ generates a hull that leaves the real line tangentially.
