Rider and Princeton Universities Present the Homotopy and Toric Spaces Workshop from February 22 to 25
Dr. Tony Bahri, professor of Mathematics at Rider, is an organizer of the Homotopy and Toric Spaces Workshop.
The departments of Mathematics at Rider and Princeton Universities will co-host a workshop that brings together several of the foremost experts in Toric Topology and Homotopy Theory from February 22 to 25 at both institutions. The three-day workshop will focus on a relatively new area of mathematics that encompasses various fields of mathematics including algebraic topology, algebraic geometry, symplectic geometry, combinatorics, robotics and theoretical physics.
Toric spaces are typically very large dimensional geometrical objects, which generally are not visualizable. As an example, one type of toric space is made from ordinary circles and discs according to a recipe that is encoded in a combinatorial object known as a polytope. Products of circles and discs are “glued” together in a way dictated by the combinatorial information. The complex movements of certain robots, for example, is governed by the structure of this sort of toric space.
Since large dimensional toric spaces cannot be pictured easily, mathematicians have constructed algebraic methods to analyze their “shape.” As noted above, the algebraic information comes from a combinatorial recipe; two toric spaces with distinct algebraic information cannot have the same shape. Several lectures at the workshop will concern the way in which the algebraic information is determined from the combinatorial recipe.
The workshop is sponsored by the Princeton Algebraic Topology Seminar, and is organized by Dr. Tony Bahri, professor of Mathematics at Rider University; Dr. Martin Bendersky, professor of Mathematics at the Graduate Center, City University of New York; and Dr. William Browder, professor of Mathematics at Princeton University.

The workshop talks will be of a specialized nature and research-based. The event is free and open to the public and attendees are asked to register with one of the organizers:
