Mathematics Seminars 
Week of 10/12/2020 


Hybrid seminars: Please be aware that hybrid seminars are reserved for IAS community members. Further, up to 8 people are allowed in Simonyi 101 at a time. Masks are required of all audience members. 

One must complete a health screening form before coming to campus for each day visiting, including when one intends to attend a hybrid seminar. It's available here: 

[ https://forms.ias.edu/form/health-screening | 
        https://forms.ias.edu/form/health-screening ] 


(Only those with an IAS account can access the form.) 

After submission, please wait until you receive an email approving your visit, if you are not immediately cleared. 

Hybrid seminars have a physical location in their listing, like Simonyi 101 or Wolfensohn Hall. 

Zoom links are now included with each seminar listing. Monday, October 12
