MAIN ZOOM link (from February 5, 2021): https://theias.zoom.us/j/97116147750?pwd=L2Fud1Y4Z2xsT3dhU2NrV0ZXd3lUQT09
(Meeting ID: 971 1614 7750 ; Passcode: 816898)
(Alternate: https://umontreal.zoom.us/j/94366166514?pwd=OHBWcGluUmJwMFJyd2IwS1ROZ0FJdz09
)
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
).
