Title: The Double Bubble Problem
Abstract: A single round soap bubble provides the least-perimeter way to enclose a given volume of air, as was proved by Schwarz in 1884. The Double Bubble Problem seeks the least-perimeter way to enclose and separate two given volumes of air. Three friends and I solved the problem in Euclidean space in 2000. In the latest chapter, Emanuel Milman and Joe Neeman recently solved the problem in Gauss space (Euclidean space with Gaussian density). The history includes results in various spaces and dimensions, some by undergraduates. Many open questions remain.
Title: The Isoperimetric Problem
Abstract: The isoperimetric problem seeks the least-perimeter way to enclose a given volume. Although the answer is well known to be the round sphere in Euclidean and some other spaces, many fascinating open questions remain. Is a geodesic sphere isoperimetric in CP^2? What is the least-perimeter tile of the hyperbolic plane of prescribed area?
Title: The Isoperimetric Problem in Spaces with Density
Abstract: Since their appearance in Perelman's 2006 proof of the Poincaré Conjecture, there has been a flood of interest in positive weights or densities on spaces and the corresponding isoperimetric problem. The talk will include recent results and open questions.
The aim of the workshop is describing major advancements in bothalgebra and number theory, such as the discovery and advancement ofbounded gaps between twin primes, and the progress on word problems forsimple groups. This workshop day aims at explaining some of theseadvancement to graduate and advanced undergraduate students.
