Spherical amoebae and a spherical logarithm map

Victor Batyrev, Megumi Harada, Johannes Hofscheier +1

Let $G$ be a connected reductive algebraic group over $C$ with a maximal compact subgroup $K$ . Let $G / H$ be a (quasi-affine) spherical homogeneous space. In the first part…

Machine Learning the Dimension of a Polytope

Tom Coates, Johannes Hofscheier, Alexander Kasprzyk

We use machine learning to predict the dimension of a lattice polytope directly from its Ehrhart series. This is highly effective, achieving almost 100% accuracy. We also use machi…

A generalization of a theorem of G. K. White

Victor Batyrev, Johannes Hofscheier

An n-dimensional simplex Δ in \R^n is called empty lattice simplex if Δ\cap\Z^n is exactly the set of vertices of Δ. A theorem of G. K. White shows that if n=3 then any empty latti…
