在概率论中,施拉姆-勒夫纳演变(Schramm–Loewner evolution,SLE)是一个平面曲线的家族以及统计力学模特的缩放极限。
应用
- Uniform spanning tree, Loop erased random walk
- 自避行走
- 普遍性 (物理学)
- 施拉姆-勒夫纳进化描述临界渗流,临界易辛模型,自避行走的缩放极限
- 统计力学模型
- 因为SLE有马尔可夫性质,所以可以用伊藤微积分来分析一下
- 共形场论
勒夫纳演变
- D 是单连通的开集。D是复杂域,但是不等于C。
- γ 是D中的一条曲线。γ 在D 的边界开始。
- 因为是单连通的,它通过共形映射等于D(黎曼映射理论)。
- 是同构。
- 是反函數。
- 在t = 0,f0(z) = z 和 g0(z) = z。
- ζ(t)是驱动函数(driving function),接受D边界上的值。
根据Loewner (1923,p. 121),Loewner方程是
的关系是
施拉姆-勒夫纳演变
SL演变是一个勒夫纳方程,有下面的驱动函数
其中 B(t) 是D边界上的布朗运动。
例如
- 若0 ≤ κ ≤ 4,曲线γ(t)几乎必然是简单曲线
- 若4 < κ < 8,γ(t) 与自身相交。
- 若 κ ≥ 8,γ(t)是space-filling的。
- 若κ = 2,曲线是Loop-erased random walk。[1][2]
- κ = 8:皮亚诺曲线
- 若 κ = 8/3,有人猜想这个SLE描述自避行走。
- κ = 3:易辛模型边界的极限
- κ = 4:高斯自由场,harmonic explorer (2005) ,[3]
- κ = 6:斯坦尼斯拉·斯米尔诺夫证明SLE6 是格子(正三角形鑲嵌)上的临界渗透的缩放极限[4][5],计算临界指数[6][7][8];证明渗流的共形不变性Smirnov (2001)[9],Cardy方程
- κ = 8:path separating UST from dual tree
属性
若SLE描述共形场论,central charge c等于
Beffara (2008) 表明了SLE的豪斯多夫维数是min(2, 1 + κ/8)。
Lawler, Schramm & Werner (2001) 用SLE6 证明Mandelbrot (1982)的猜想:平面布朗运动边界的分形维数是4/3。
Rohde和Schramm表明了曲线的分形维数是
