Abstract: Liouville quantum gravity (LQG) is a theory of random fractal surfaces with origin in the physics literature in the 1980s. Most literature is about LQG with matter central charge ${\mathbf c}\in(-\infty,1]$. We study a discretization of LQG which makes sense for all ${\mathbf c} \in (-\infty,25)$. Based on a joint work with Gwynne, Pfeffer, and Remy.
