18.177 Topics in Stochastic Processes: Random Planar Maps,
Liouville Quantum Gravity, and SLE (Fall 2014)
(The first image is a random quadrangulation with 25,000 faces
embedded (non-isometrically) into 3-dimensional space and was
taken from here . The second
image is a circle packing, generated with CirclePack , of a random
quadrangulation. The final image is a space-filling SLE(6). Additional images can be found here
and here .)
