高斯自由场与双连通域上的SLE(4)

The Gaussian free field and SLE(4) on doubly connected domains

Christian Hagendorf, Denis Bernard, Michel Bauer

摘要:

已知高斯自由场的能级线与SLE(4)有关。它显示了这种关系如何允许定义弦SLE(4)过程的双连通域,描述的痕迹,锚定在两个边界组件之一。过程的精确性质取决于施加在第二边界分量上的共形不变边界条件。在标准Dirichlet和Neumann条件下,将Schramm公式推广到双连通域,并建立了与布朗桥第一出口问题的关系。对于在自对偶半径处紧化的自由场,扩展对称性导致了一类以SU(2)元素为参数的共形不变边界条件。它展示了如何将SLE(4)扩展到这个设置。这允许一个新的通道概率的推导一个香格里拉Schramm,连续插值从狄利克雷诺依曼条件。

英文摘要:

The level lines of the Gaussian free field are known to be related to SLE(4). It is shown how this relation allows to define chordal SLE(4) processes on doubly connected domains, describing traces that are anchored on one of the two boundary components. The precise nature of the processes depends on the conformally invariant boundary conditions imposed on the second boundary component. Extensions of Schramm's formula to doubly connected domains are given for the standard Dirichlet and Neumann conditions and a relation to first-exit problems for Brownian bridges is established. For the free field compactified at the self-dual radius, the extended symmetry leads to a class of conformally invariant boundary conditions parametrised by elements of SU(2). It is shown how to extend SLE(4) to this setting. This allows for a derivation of new passage probabilities a la Schramm that interpolate continuously from Dirichlet to Neumann conditions.
