Abstract
The classical Hardy space H2 has a
natural structure of a module over the algebra of polynomials
C[z]. In this setting the theorem of Beurling
describes all closed C[z]-submodules of H2. In
this paper we prove a Beurling-type theorem for H2 as a
module over a finitely generated polynomial algebra.
