ACTIVITIES

I am one of the organizers of Handayama Geometry and Algebra seminar from December 2016. The organizers are teachers in OUS: Hiraku Abe, Shinzo Bannai, Ryoichi Kase, Masayuki Kawashima, Taiki Shibata and myself (Takeshi Ikeda and Tomoo Matsumura were also organizers from December 2016 to March 2020).

I organized the 50th Symposium on Transformation Groups at NPD Kashikaigishitsu Okayama Takashimaya from 22nd--24th November 2024. The co-organizer was Shunsuke Tamura (National Institute of Technology, Tsuyama College).

I co-organized Workshop on toric topology 2024 in Shanghai (online) from 13th--14th August 2024. The organizers were Zhi Lu (Fudan University), Ping Li (Fudan University), Haozhi Zhang (Huazhong University of Science and Technology) and myself.

I co-organized the 49th Symposium on Transformation Groups at Core Communicate in Nagasaki from 1st--3rd December 2023. The main organizer is Prof. Takao Sato (Tokyo U of Science).
