Beurling's Theorem for Valuation Hilbert Modules and Several Complex Variables

Complex Variables 2023-06-23 v4

Abstract

We develop a theory of Valuation Hilbert Modules and prove a version of Beurling's theorem for these. Then we apply our version of Beurling's theorem to obtain complete descriptions of the closed invariant subspaces of a number of Hilbert spaces of analytic functions in several complex variables, including H2H^2 of the polydisk the ball, and bounded symmetric domains, and weighted A2A^2 spaces on complex analytic manifolds.

31 pages. Changed some terminology and added material on $R_1$ inner functions. v3: Added additional matrial on $ R_1 $ inner functions and their relation to $ A^p_\alpha $ inner functions. v4 : Revised terminology for valuation Hilbert modules. Added complete proofs of the Minimum Value Theorem, and the 4th Projection Lemma, plus other additions and corrections. arXiv admin note: text overlap with arXiv:2109.00695, arXiv:2108.12272
