Extremal conditional independence for Hüsler-Reiss distributions via modular functions
Karel Devriendt, Ignacio Echave-Sustaeta Rodríguez, Frank Röttger
We study extremal conditional independence for Hüsler-Reiss distributions, which is a parametric subclass of multivariate Pareto distributions. As the main contribution, we introdu…

Tropical toric maximum likelihood estimation
Emma Boniface, Karel Devriendt, Serkan Hoşten
We consider toric maximum likelihood estimation over the field of Puiseux series and study critical points of the likelihood function using tropical methods. This problem translate…

The Two Lives of the Grassmannian
Karel Devriendt, Hannah Friedman, Bernhard Reinke +1
The real Grassmannian is both a projective variety (via Plücker coordinates) and an affine variety (via orthogonal projections). We connect these two representations, and we develo…
