Abstract:
Enumerative algebraic geometry counts the solutions to certain geometric constraints. Numerical nonlinear algebra determines these solutions for any given instance. This talk illustrates how these two fields complement each other, especially in the light of emerging new applications. We start with a wonderful piece of 19th century geometry, namely the 3264 conics that are tangent to five given conics in the plane. Thereafter we turn to current problems in statistics and data science, with focus on the maximum likelihood estimation for linear Gaussian covariance models.
