AHGT Focus Workshops & Lecture Series
Focus events to introduce and report on the latest topics and progress of the arithmetic homotopy and Galois theory program.
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.

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.
Seminars for early-career researchers
Some occasional events organized by the nodes of the network:
- Rational Points and Geometry at RIMS Kyoto (Aug. 10-23, 2023; 3x 2hrs) by H. Liu, IMJ-PRG.
Ookayama Youth Seminar in Algebra - 大岡山代数系若手セミナー
The Ookayama Youth Seminar in Algebra is a seminar for Mx students, and PhD and early career postdoctoral researchers of Tokyo Institute of Technology and its surrounding. The seminar takes place every two-weeks in Tokyo Institute of Technology and is organized by Slack.
Please contact the organizers T. Asayama or N. Yamaguchi.
