Because a Typhoon is approaching to Tokyo area on Aug.8-9, we will change the schedule on Aug.9 substantially.

We are planning to start the workshop from the afternoon of Aug.9.

Please check the latest update on this web page.

(The update will be posted on Aug.8, early morning)

Working Workshop on

Calabi-Yau Varieties and Related Topics

Theme: In this two day's working workshop, we will discuss arithmetic and geometry related to Calabi-Yau manifolds. Our primary focus will be having discussions and exchanging ideas among participants, not only experts but also non-experts, in a rather informal atmosphere.

From Aug.9 (Thu) to Aug.10 (Fri), 2018

Gakushuin University, 1号館301号室
