SLE和自由场:配分函数和耦合

SLE and the free field: Partition functions and couplings

Julien Dubedat

摘要:

Schramm-Loewner演化($\SLE$)是平面单连通区域中的随机曲线;在这样的区域中的无质量(欧几里德)自由场是随机分布。两者都具有共形不变性的性质。本文探讨了这两个客体之间的某些关系。我们建立了不同版本的$\SLE$和自由场与适当的边界条件之间的配分函数的身份,这涉及$ζ$-正则化和Polyakov-Alvarez共形异常公式。我们继续建设的耦合$\SLE$与自由场,表明,在精确的意义上,弦$\SLE$是一个随机的“微分”方程驱动的自由场的解决方案。存在性,唯一性的法律,和路径的唯一性,这些SDES一般PDMATHAMO证明。

英文摘要:

Schramm-Loewner Evolutions ($\SLE$) are random curves in planar simply connected domains; the massless (Euclidean) free field in such a domain is a random distribution. Both have conformal invariance properties in law. In the present article, some relations between the two objects are studied. We establish identities of partition functions between different versions of $\SLE$ and the free field with appropriate boundary conditions; this involves $ζ$-regularization and the Polyakov-Alvarez conformal anomaly formula. We proceed with a construction of couplings of $\SLE$ with the free field, showing that, in a precise sense, chordal $\SLE$ is the solution of a stochastic "differential" equation driven by the free field. Existence, uniqueness in law, and pathwise uniqueness for these SDEs are proved for general $κ>0$.
