Dr. Markus Röser (Universität Hannover) "Hyperkähler Implosion"

05.06.2015 von 11:30 bis 12:30

LMS 4 - Raum 424 - Kleiner Hörsaal

Abstract:

Symplectic Implosion is an abelianisation procedure for Hamiltonian group actions on symplectic manifolds with interesting links to non-reductive geometric invariant theory and toric geometry. In this talk we shall explore an analogue of this construction in hyperkähler geometry using gauge-theoretic techniques. This is joint work in progress with Andrew Dancer and Frances Kirwan.
