Junior Prof. Dr. Ariyan Javanpeykar

I obtained my PhD in June 2013 under the supervision of J.-B. Bost (Paris-Sud 11), Bas Edixhoven (Leiden), and Robin de Jong (Leiden). From July 2013 until November 2015 I was a post-doctoral fellow supported by the SFB/Transregio 45.

My research is concerned with Arakelov theory, Belyi's theorem, Lang-Vojta's conjecture on rational points, Kobayashi's notion of hyperbolicity, Shimura varieties, period domains, non-archimedean hyperbolicity, and
dynamical systems in arithmetic geometry. In my work I employ algebraic stacks, Hodge theory, and arithmetic geometry. Below you will find a list of papers and three videos of some talks I gave on my research.
