Singular Hilbert modules on Jordan-Kepler varieties

Functional Analysis 2019-05-10 v1

Abstract

We study submodules of analytic Hilbert modules defined over certain algebraic varieties in bounded symmetric domains, the so-called Jordan-Kepler varieties VV_\ell of arbitrary rank .\ell. For >1\ell>1 the singular set of VV_\ell is not a complete intersection. Hence the usual monoidal transformations do not suffice for the resolution of the singularities. Instead, we describe a new higher rank version of the blow-up process, defined in terms of Jordan algebraic determinants, and apply this resolution to obtain the rigidity of the submodules vanishing on the singular set.
