Young Researchers Workshops

One of the goals of the AHGT IRN is the coordination and support of independant activities for early-career researchers, i.e. Master students, PhD students and postdoctoral researchers, in terms of short and topic-focus oriented workshops and seminars.

Atelier de Géométrie Arithmétique - 数論幾何学のアトリエ

[Atelier23] Atelier de Géométrie Arithmétique 2023 - Local-global principles and patching method

Local-global principles and the patching method

Paris & RIMS Kyoto [Hybrid] June 27, 2023 Org.: E. Boughattas, S. Philip & N. Yamaguchi

Webpage of the workshop

The AHGT Ateliers are one-day events organized by and for early-career researchers to discover and get a working understanding of both fundamental and hot topics in Arithmetic and Homotopic Galois Theory.
Talks are distributed in advance among participants, who also propose and vote the next event topic.
