共形随机几何

Conformal Random Geometry

Bertrand Duplantier

摘要:

在这些注释中,给出了平面或半平面中保角不变标度曲线或界面的普适分形几何的全面描述。本方法的重点是推导临界指数与相互作用的随机路径,通过利用其潜在的量子引力结构。后者将平面中的指数与随机晶格上的指数相关联,即,在波动的度量,使用所谓的Knizhnik,Polyakov和Zamolodchikov(KPZ)地图。这是在随机矩阵理论和共形场论的框架内完成的,并应用于几何临界模型,如布朗路径,自避免行走,渗流,更一般地说,O(N)或Q状态Potts模型,最后但并非最不重要的是,Schramm的随机Loewner演化(SLE_kappa)。这些笔记可以被认为是对Wendelin Werner(2006年菲尔兹奖得主!)的补充,“随机共形不变系统的一些最新方面,”arXiv:math。PR/0511268。

英文摘要:

In these Notes, a comprehensive description of the universal fractal geometry of conformally-invariant scaling curves or interfaces, in the plane or half-plane, is given. The present approach focuses on deriving critical exponents associated with interacting random paths, by exploiting their underlying quantum gravity structure. The latter relates exponents in the plane to those on a random lattice, i.e., in a fluctuating metric, using the so-called Knizhnik, Polyakov and Zamolodchikov (KPZ) map. This is accomplished within the framework of random matrix theory and conformal field theory, with applications to geometrical critical models, like Brownian paths, self-avoiding walks, percolation, and more generally, the O(N) or Q-state Potts models and, last but not least, Schramm's Stochastic Loewner Evolution (SLE_kappa). These Notes can be considered as complementary to those by Wendelin Werner (2006 Fields Medalist!), ``Some Recent Aspects of Random Conformally Invariant Systems,'' arXiv:math.PR/0511268.
