School on

Dates and Location. June 18–22, 2018, at Institut Henri Poincaré (IHP), in the center of Paris (map, directions).
Presentation. This is a oneweek school devoted to lowdimensional geometry and topology, from both the viewpoints of mathematicians and computer scientists. It is aimed at graduate students and researchers in mathematics and computer science interested in geometric or topological aspects. This includes, not exhaustively, mathematicians working in differential, Riemannian, or topological geometry; and computer scientists working in computational geometry or topology. The goal is to foster interactions between these communities.
Speakers. The two main speakers, each giving about 90 minutes of lectures each of the five days of the week, are:
Jeff Erickson
(University of Illinois at UrbanaChampaign, USA)
Tentative title: Twodimensional computational topology Tentative abstract (see here for a more detailed tentative plan of the lectures). This series of lectures will describe recent and notsorecent works in computational topology of curves in the plane and on surfaces. Combinatorial and algorithmic aspects will be discussed. 
Joel Hass
(University of California at Davis, USA)
Title: Algorithms and complexity in the theory of knots and manifolds Abstract (see here for a more detailed tentative plan of the lectures). These lectures will introduce algorithmic procedures to study Knots and 3dimensional manifolds. Algorithmic questions have been part of the study of manifolds since the time of Dehn, and are finding increasing practicality as algorithms and hardware improve. The study of algorithmic procedures often points the way to interesting directions in the theoretical study of manifolds. We’ll begin by reviewing an easy algorithm to classify 2manifolds, and then outline Markov's argument for the undecidability of 4manifold recognition. We’ll then turn to 3dimensions...(read more). 
The following researchers will also give a presentation:
Registration. Registration is free but mandatory. Register here now! (Deadline was March 15; we can still accept some participants, but will close the registration when we cannot accept more.)
