Hyperkahler implosion

Date: 
Monday 27th June 2011 - 11:30 to 12:30
Venue: 
INI Seminar Room 1
Abstract: 
Symplectic implosion is a construction in symplectic geometry due to Guillemin, Jeffrey and Sjamaar, which is related to geometric invariant theory for non-reductive group actions in algebraic geometry. This talk (based on joint work in progress with Andrew Dancer and Andrew Swann) is concerned with an analogous construction in hyperkahler geometry.
