Seminar 

Interactions between symplectic geometry, combinatorics and number theory (14722.0073)

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