                Title:  Geometry, Duality, and Large Scale Phenomena in the Homotopy Groups of Spheres


                Abstract:
The core project of homotopy theory is to calculate the homotopy classes of maps between finite simplicial complexes.
                However, even when the complexes are spheres, low dimensional calculations appear noisy and random. The key to developing a
                structure was to find large-scale periodic phenomena, a point of view initiated by Adams in the 1960s using K-theory. Forty years
                later we have gotten very good at this, especially after work of Hopkins and his coauthors connecting this study to arithmetic geometry,
                including the geometry of elliptic curves. In this talk, I hope to offer a window into this world, and explain some of the beautiful
                patterns and symmetries we have found. (Contact Person: Anna Marie Bohmann)
