The Belyi degree is computable

Ariyan Javanpeykar, John Voight

We exhibit an algorithm that, given input a curve $X$ over a number field, computes as output the minimal degree of a Belyi map $X \to P^{1}$ .

Invariants of Fano varieties in families

Frank Gounelas, Ariyan Javanpeykar

We show that the Picard rank is constant in families of Fano varieties (in arbitrary characteristic) and we moreover investigate the constancy of the index.

Horospherical stacks

Ariyan Javanpeykar, Kevin Langlois, Ronan Terpereau

We prove structure theorems for algebraic stacks with a reductive group action and a dense open substack isomorphic to a horospherical homogeneous space, and thereby obtain new exa…
