Richard Rimanyi (UNC Chapel Hill): Elliptic cohomology

Abstract: Assigning characteristic classes to singular varieties is an effective
way of studying their local and global properties. Relations to physics
indicate that the right habitat of these characteristic classes is
elliptic cohomology. In this talk we will explore the notion of elliptic
cohomology, and one of its advantages, namely its role in (a
mathematically precise level of) 3d mirror symmetry.
