SUMMARY:Symplectic groups and Cobordism categories - Fabian Hebestreit (B
 ielefeld)
DTSTART:20251119T160000Z

CONTACT:Oscar Randal-Williams
DESCRIPTION:In joint work with Land and Nikolaus\, we recently computed a 
 large part of the stable cohomology of symplectic groups over the integers
 . In the talk I will try to explain our approach highlighting two perhaps 
 surprising facts: That we import surgery techniques from differential topo
 logy and that it is necessary to include derived symplectic forms to facil
 itate this.
