RTG Seminar on Number Theory Seminar

Metric Algebraic Geometry
Tuesday, January 19, 2021
3:00-4:50 PM
Virtual Off Campus Location
Pre-talk for grad students at 3pm. Main talk at 4pm.

Pre-talk Title and Abstract: "What is a Chow ring?"

In this pre-seminar talk, we will introduce the Chow ring, a basic tool of intersection theory. We will compute examples of Chow rings and show how they can be used to answer enumerative questions in algebraic geometry.

Main talk abstract: Metric algebraic geometry is a term proposed for the study of properties of real algebraic varieties that depend on a distance metric. The distance metric can be the Euclidean metric in the ambient space or a metric intrinsic to the variety. In this talk, we introduce metric algebraic geometry through a discussion of Voronoi cells, bottlenecks, offset hypersurfaces, and the reach of an algebraic variety. We also show applications to the computational study of the geometry of data with nonlinear models.
