Lecture Notes on Computational Conformal Geometry

This is the lecture notes given in my seminar "computational conformal geometry". It covers the major concepts in topology, differential geometry, Riemann surface theories related to conformal geometry, and many major algorithms for computing conformal structures. Most directly related applications are demonstrated. [PDF]


Tutorial on Euclidean Ricci Flow

This is an early version of the tutorial introducing Euclidean Ricci flow. It includes some examples for computing flat metrics on surfaces with a single cone singularity, in other words, all curvature is concentred on a single point. [PDF]
