## Symplectic Zoominar (CRM-Montreal, Princeton/IAS, Tel Aviv, and
Paris).

**Current talk announcements and other info

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. **W****e 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*
