Seminar 

​

Interactions between symplectic geometry, combinatorics and number theory (14722.0068)

​

or

​

The "ColMar" Interactions

​

​

 

 

 

This semester the seminar "Interactions" will join the teams of two universities: that of Cologne, and that of Marburg, therefore the name "ColMar* Interactions". The goal for this semester is to explain some very recent developments in the field of equivariant symplectic geometry. In particular, positive monotone complexity one spaces as well as classification results of GKM spaces will be treated. 

​

The organisers are:

​

Oliver Goertsches (goertsch@mathematik.uni-marburg.de)

Panagiotis Konstantis (pako@mathematik.uni-marburg.de)

myself (sabatini@math.uni-koeln.de)

​

 

It will be held online via Zoom every other Thursday (see below) at 14:45 Cologne time (CET).

If you are interested and would like the link to the Zoom-Meeting, please send us an email.

* It is also worth noticing that in Italian "colmare" means "to bridge", and we like bridges, because they allow interactions...
