TITLE | Two-curve Green’s function for Schramm-Loewner evolution |

ABSTRACT | Schramm-Loewner evolution (SLE$_\kappa$) is a one-parameter family of random fractal curves growing in plane domains. Given an SLE$_\kappa$ curve $\gamma$ with $\kappa\in(0,8)$ in a domain $D$ and a point $z_0$, the Green's function for $\gamma$ at $z_0$ is the limit $G(z_0):= \lim_{r\downarrow 0} r^{-\alpha} \mathbb{P}[\mbox{dist}(z_0,\gamma) \less r]$, for some positive exponent $\alpha$, if the limit converges and is not trivial, i.e., not zero. There are several variations. The $z_0$ may be an interior point or a boundary point of $D$. In the former case $\alpha$ is related to the Hausdorff dimension $d$ of $\gamma$ by $\alpha=2-d=1-\frac\kappa 8$. The single point $z_0$ may be replaced by a number of points $z_1,\dots, z_n$. |
