Sampling and Interpolation in Bargmann-fock Spaces of Polyanalytic Functions

چکیده

We give a complete characterization of all lattice sampling and interpolating sequences in the Fock space of polyanalytic functions (polyFock spaces), displaying a ”Nyquist rate” which increases with the degree of polyanaliticity. This is done introducing a unitary mapping between vector valued Hilbert spaces and poly-Fock spaces. This mapping extends Bargmann ́s theory to polyanalytic spaces. Then we connect the mapping to Gabor transforms with Hermite windows and apply duality principles from time-frequency analysis in order to reduce the problem to a ”purely holomorphic” situation.

Traces of Functions in Fock Spaces on Lattices of Critical Density

We are interested in describing the set of values c = (cλ)λ∈Λ such that there exists some function f in a Fock space satisfying the condition f |Λ = c where Λ is a sequence that ‘just fails’ to be interpolating. While we shall prove our results in a more general context, we begin by introducing the problem in the classical Bargmann-Fock space, where the results are more easily digestible. We de...

Interpolation and Sampling Hypersurfaces for the Bargmann-fock Space in Higher Dimensions

ABSTRACT. We study those smooth complex hypersurfaces W in C having the property that all holomorphic functions of finite weighted L norm on W extend to entire functions with finite weighted L norm. Such hypersurfaces are called interpolation hypersurfaces. We also examine the dual problem of finding all sampling hypersurfaces, i.e., smooth hypersurfaces W in C such that any entire function wit...

Density Theorems for Sampling and Interpolation in the Bargmann-fock Space

We give a complete description of sampling and interpolation in the Bargmann-Fock space, based on a density concept of Beurling. Roughly speaking, a discrete set is a set of sampling if and only if its density in every part of the plane is strictly larger than that of the von Neumann lattice, and similarly, a discrete set is a set of interpolation if and only if its density in every part of the...

The Lee–yang and Pólya–schur Programs. Iii. Zero-preservers on Bargmann–fock Spaces

We characterize linear operators preserving zero-restrictions on entire functions in weighted Bargmann–Fock spaces. This extends the characterization of linear operators on polynomials preserving stability (due to Borcea and the author) to the realm of entire functions, and translates into an optimal, albeit formal, Lee–Yang theorem.

Zero Sets for Spaces of Analytic Functions

We show that under mild conditions, a Gaussian analytic function F that a.s. does not belong to a given weighted Bergman space or Bargmann–Fock space has the property that a.s. no non-zero function in that space vanishes where F does. This establishes a conjecture of Shapiro (1979) on Bergman spaces and allows us to resolve a question of Zhu (1993) on Bargmann–Fock spaces. We also give a simila...
