Workshop on Gestalt
- Date
- September 24 (Thu) 10:00 - September 30 (Wed) 17:00, 2026 (JST)
- Speaker
-
- Ko Aoki (Postdoc, University of Copenhagen, Denmark)
- Language
- Japanese
- Host
- Takumi Maegawa, Yutaro Mikami, Hiroyasu Miyazaki
Note. The lectures will be given in Japanese. This workshop will be jointly organized by RIKEN AIP.
During this five-day workshop, we will hold a learning seminar and intensive lectures on gestalt theory, which was recently developed by Scholze and Stefanich.
Gestalt theory is a new geometric framework that unifies various derived analytic geometry and higher sheaf theory, building on the foundations of higher and derived category theory.
At this event, we will host Ko Aoki, who has contributed to the foundations and development of the theory, for the intensive lecture session.
During the first three days of the workshop, we will feature tutorial lecture sessions, presented by the participants. All lectures will be given in Japanese, with the aim of promoting the dissemination and development of gestalt theory in Japan.
