Abstract

We propose to investigate concrete geometric and topological properties related to hyperkähler manifolds, existence of differentiable structures, and of relevant deformations. In particular, we also propose to investigate what geometric structures (hypercomplex, quaternionic kahler, hyperkähler, etc) arise in nonsingular locus of the moduli spaces of instanton bundles over complex projective spaces of dimension n. For n=2, such space is known to cary a hyperkähler metric; the case n=3 is open, and already of great interest. (AU)
