from February 5, 2021): https://theias.zoom.us/j/97116147750?pwd=L2Fud1Y4Z2xsT3dhU2NrV0ZXd3lUQT09  (Meeting ID: 971 1614 7750 ; Passcode: 816898)

Date and hour:  Fridays, 9:15 - 10:45 (Montreal/Princeton hour).


Regular research talks are of 60 minutes; 30 minutes  are reserved for discussion at the end of each talk (see VARIA below).


It is intended that talks be accessible to a global community in symplectic geometry/topology and beyond (thus, they should contain an  introduction of interest to a broad audience). 


The Zoominar promotes an atmosphere of collegiality, equity and respect and is committed to creating a welcoming and  inclusive environment for all participants, enabling them to fully focus on mathematics.




Once a month we intend to have a seminar consisting of three 20 min talks (followed each by 10 min of discussion time) reserved to young researchers/recent PhD's. In case you want to talk or to nominate someone,
see VARIA 4 below

Varia:


1. Please do not hesitate to ask questions: first indicate your intention (or even the question) by chat, then, when invited by the host/organizer, use your microphone and  video (if available).

3. There will be 30 min at the end of each talk reserved for discussion. The first 15 minutes (roughly) are, mainly, for questions addressed to  the speaker. After that, questions and answers may involve different participants.

3. We post links to the slides of the talks as well as links to recordings of the talks.

4.  We intend to have once a month a seminar consisting of three 20min talks (followed each by 10min of discussion time) given by young researchers/recent PhD's. Suggestions, nominations, and volunteers  (including a title and short abstract) should be sent to Egor Shelukhin at  egorshel@gmail.com (with cc to  octav.cornea@gmail.com ).
