Likelihood Geometry of the Squared Grassmannian

Abstract

We study projection determinantal point processes and their connection to the squared Grassmannian. We prove that the log-likelihood function of this statistical model has (n1)!/2(n - 1)!/2 critical points, all of which are real and positive, thereby settling a conjecture of Devriendt, Friedman, Reinke, and Sturmfels.
