Seminar 

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

or

The "ColMar" Interactions

 

 

 

The seminar "Interactions" joins the teams of two universities: that of Cologne, and that of Marburg, therefore the name "ColMar* Interactions". The goal is to explain some very recent developments in the field of equivariant topology and equivariant symplectic geometry.

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 on the dates and times listed below.

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

The schedule, so far, is the following (click on the title to see the abstract):


21.10.21, 14:30-16:00: Nicholas Lindsay (U. of Cologne), "Hamiltonian S^1-actions on complete intersections"


17.11.21, 12:30-14:00: Anton Ayzenberg (HSE University), "Face posets of equivariantly formal torus actions"


09.12.21, 14:30-16:00: Chris McDaniel (Endicott College), "A GKM Description for the Equivariant Coinvariant Ring of a Pseudo Reflection Group"


16.12.21, 14:30-16:00: Lisa Jeffrey (U. of Toronto), "Poisson maps between character varieties: gluing and capping"

Please note that the time zone above is GMT+1  

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