Description: Scientific and engineering disciplines are in increasing need of effective methods for distilling and analyzing structural information from vast quantities of complex data. In recent years, ideas and methods from algebraic topology, combined with the development of fast algorithms and user-friendly software, have proven valuable in this endeavor. This program aims at stimulating and enhancing collaboration between experts in several areas of applied and computational topology, together with scientists actively working on problems the solution of which might require topological insights and machinery. It will focus on the following three areas of investigation:
- Topological and statistical analysis of shapes, images, and multi-dimensional data sets
- Stochastic topology
- Topological contributions to the theory of concurrent computation and computer networks
Associated Events: The program comprises two parts:
- A spring school and an international interdisciplinary conference (April 24 - May 6, 2017)
- Collaboration between experts in applied and computational algebraic topology, both senior and junior, including focused seminars (September 4 - 29, 2017)
