Online Noncommutative Geometry Seminar


We would like to invite all friends interested in Noncommutative Geometry to join our online seminar.

The seminar will be held on Wednesday at 6 p.m. (UTC), which is the following time,
 
Canada Atlantic 3 p.m.-4 p.m., U.S. Eastern 2 p.m.-3.p.m., U.S. Central 1 p.m.-2 p.m., U.S. Mountain, 12 p.m.-1 p.m., U.S. Pacific, 11 a.m.-12 p.m., U.S. Hawaii, 8 a.m.-9 a.m.

Please contact the organizers, Xiang Tang (xtang@math.wustl.edu) and Guoliang Yu (guoliangyu@math.tamu.edu), for the access information of the zoom meetings.

This seminar ended on December 16, 2020.  We are starting a new seminar, Global Noncommutative Geometry Seminar (Americas), together with Katia Consani, Guillermo Cortiñas, Nigel Higson, Masoud Khalkhali in January 2021 with the new seminar website, https://globalncgseminar.org
