Description

Algebraic Topology is not only a highly-deveolped “abstract” field of “pure” Mathematics – it also offers an effective and versatile toolbox for applications in diverse fields such as Combinatoics, Discrete Geometry, Statistics and Data Analysis. Some of these applications rely on topological ideas, concepts and theorems that allow one to measure hidden "topological" structures, such as connectivity or obstructions to mapping. Others rely on the explicit computation of topological invariants, such as homology or linking numbers. The goal of the Introductory Worskshop for the MSRI program will be to survey the "Algebraic Topology toolbox" from the view of applications, and to present areas of current interest where topological tools have been applied, are being employed or should be brought into play. Invited speakers include: Robert Ghrist (University of Illinois), Sergio Rajsbaum (Universidad Nacional Autonoma de Mexico), Konstantin Mischaikow (Georgia Institute of Technology), Shmuel Weinberger (New York University), John Harer (Duke University), Susan Holmes (Stanford University), Gunnar Carlsson (Stanford University), Guenter Ziegler (Technische Universität, Berlin), Eric Babson (University of Washington), Persi Diaconis (Stanford University), Yuliy Baryshnikov (Bell Laboratories), Rade Zivaljevic (Mathematical Institute SANU Belgrade).
