Abstract:
Schramm-Loewner Evolution (SLE$_\kappa$) is a one-parameter family of random fractal curves that describes the conjectural scaling limits of interfaces in two-dimensional statistical mechanics models. In this talk, I will present a result with Haoyu Liu (PKU) showing that there exists $\delta>0$ such that for $\kappa \in (8 - \delta, 8)$, the range of an SLE$_\kappa$ curve almost surely contains a topological Sierpiński carpet. Combined with a result of Ntalampekos (2021), this implies that in this parameter range, SLE$_\kappa$ is almost surely conformally non-removable, and the conformal welding problem for SLE$_\kappa$ does not have a unique solution. Our result also implies that for $\kappa \in (8 - \delta, 8)$, the adjacency graph of the complementary connected components of the SLE$_\kappa$ curve is disconnected.
During this talk, I will explain the main ideas inspired by Mandelbrot’s fractal percolation model and discuss some open problems.
