Inter-universal Teichmüller Theory (IUT) Summit 2021
RIMS workshop, September 7 - September 10 2021



Shinichi Mochizuki, Yuichiro Hoshi, Ivan Fesenko, Yuichiro Taguchi.

This workshop is one of four workshops of special RIMS year "Expanding Horizons of Inter-universal Teichmüller Theory".

This workshop will differ from previous workshops on inter-universal Teichmüller theory in that it will be directed primarily toward advanced learners of the theory, as well as researchers who have already acquired a thorough understanding of the theory.

The talks of the workshop will focus on issues related to the exposition or formulation of the theory from a more advanced point of view, as well as on recent new research developments related to the theory.

Invited speakers:

Benjamin Collas (Univ. Lille France/RIMS, Kyoto Univ., Japan),
Ivan Fesenko (Univ. Nottingham, UK),
Yuichiro Hoshi (RIMS, Kyoto Univ., Japan),
Arata Minamide (RIMS, Kyoto Univ., Japan),
