A SYMPLECTIC CUT
This is the website of the symplectic cut seminar, which meets online weekly and served on open source software.
There is also a
Matrix chat room where you can find annoucements and have discusssions related to the seminar. You can access it by creating an account at
Freemath (make sure to choose Other so that your account is created in freemath.xyz) and joining the room called Symplectic Cut.
Seminar time in Autumn 2020 : Wednesday 3 - 5 pm UTC+01:00.
Seminar location : BBB server (the link for each talk is e-mailed to the participants before the seminar)
The theme for this term is Homological Mirror Symmetry for cluster varieties.
We are collecting some references here (please send me more references).
