Jeff Erickson - Lecture 1 - Two-dimensional computational topology - 18/06/18

School on Low-Dimensional Geometry and Topology: Discrete and Algorithmic Aspects (http://geomschool2018.univ-mlv.fr/) Jeff Erickson (University of Illinois at Urbana-Champaign, USA) Two-dimensional computational topology - Lecture 1 Abstract: This series of lectures will describe recent and not-so-recent works in computational topology of curves in the plane and on surfaces. Combinatorial and algorithmic aspects will be discussed. 1. Historical roots of computational topology topological invariants, combinatorial encodings, and algorithms angle sums, rotation numbers, regular homotopy winding numbers, signed area, point-in-polygon graphs and Euler tours Gauss/Dowker code planarity ---------------------------------- Vous pouvez nous rejoindre sur les réseaux sociaux pour suivre nos actualités.
