## Chinese dragons and mating trees

Abstract: What is the right way to think of a “random surface” or a “random planar graph”? How can one explain the dendritic patterns that appear in snowflakes, coral reefs, lightning bolts, and other physical systems, as well as in toy mathematical models inspired by these systems? How are these questions related to random walks and random fractal curves (in particular the famous SLE curves)? How are they related to conformal matings of Julia sets? To string theory? To statistical mechanics?

To begin to address these questions, I will introduce and explain the “quantum Loewner evolution” (QLE), which is a family of growth processes closely related to SLE.
