Differential Equations for Gaussian Statistical Models with Rational Maximum Likelihood Estimator
Carlos Améndola, Lukas Gustafsson, Kathlén Kohn +2
We study multivariate Gaussian statistical models whose maximum likelihood estimator (MLE) is a rational function of the observed data. We establish a one-to-one correspondence bet…

Conditional Euclidean distance optimization via relative tangency
Sandra Di Rocco, Lukas Gustafsson, Luca Sodomaco
We introduce a theory of relative tangency for projective algebraic varieties. The dual variety of a variety relative to a subvariety is the set of hyperplanes t…
