Quantization of Yang--Mills metrics on holomorphic vector bundles

Abstract

We investigate quantization properties of Hermitian metrics on holomorphic vector bundles over homogeneous compact Kähler manifolds. This allows us to study operators on Hilbert function spaces using vector bundles in a new way. We show that Yang--Mills metrics can be quantized in a strong sense and for equivariant vector bundles we deduce a strong stability property which supersedes Gieseker-stability. We obtain interesting examples of generalized notions of contractive, isometric, and subnormal operator tuples which have geometric interpretations related to holomorphic vector bundles over coadjoint orbits.
