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.
