**Speaker:** Bernd Sturmfels (MPI Leipzig and UC Berkeley)

**Title: **Algebraic Statistics with a View towards Physics

**Venue: **virtual and 20 Garden Street, Room G10

**Abstract:** We discuss the algebraic geometry of maximum likelihood estimation from the perspective of scattering amplitudes in particle physics. A guiding examples the moduli space of n-pointed rational curves. The scattering potential plays the role of the log-likelihood function, and its critical points are solutions to rational function equations. Their number is an Euler characteristic. Soft limit degenerations are combined with certified numerical methods for concrete computations.
