Title: Trihyperkähler Reduction And Instanton Bundles On (formula Presented.)
Author: Jardim M.
Verbitsky M.
Abstract: A trisymplectic structure on a complex 2n-manifold is a three-dimensional space Ω of closed holomorphic forms such that any element of has constant rank 2n, n or zero, and degenerate forms in belong to a non-degenerate quadric hypersurface. We show that a trisymplectic manifold is equipped with a holomorphic 3-web and the Chern connection of this 3-web is holomorphic, torsion-free, and preserves the three symplectic forms. We construct a trisymplectic structure on the moduli of regular rational curves in the twistor space of a Trihyperkähler manifold, and define a trisymplectic reduction of a trisymplectic manifold, which is a complexified form of a Trihyperkähler reduction. We prove that the trisymplectic reduction in the space of regular rational curves on the twistor space of a Trihyperkähler manifold M is compatible with the Trihyperkähler reduction on M. As an application of these geometric ideas, we consider the ADHM construction of instantons and show that the moduli space of rank r, charge c framed instanton bundles on ℂℙ3 is a smooth trisymplectic manifold of complex dimension 4rc. In particular, it follows that the moduli space of rank two, charge c instanton bundles on ℂℙ3 is a smooth complex manifold dimension 8c-3, thus settling part of a 30-year-old conjecture.
