Let $(G,+)$ be a compact, abelian, and metrizable topological group. In this group we take $g\in G$ such that the corresponding automorphism $\tau _g$ is ergodic. The main result of this paper is a new ergodic theorem for functions in $L^1(G,M)$ , wh

We study the existence of Gabor orthonormal bases with window the characteristic function of the set Ω = [ 0 , α ] ∪ [ β + α , β + 1 ] of measure 1, with α , β > 0 . By the symmetries of the problem, we can restrict our attention to the case

Let Ω be a smooth, bounded, convex domain in Rn and let Λk be a finite subset of Ω. We find necessary geometric conditions for Λk to be interpolating for the space of multivariate polynomials of degree at most k. Our results are asymptotic in k.

Let $\mu$ be a probability measure on $\mathbb{T}$ that is singular with respect to the Haar measure. In this paper we study Fourier expansions in $L^2(\mathbb{T},\mu)$ using techniques from the theory of model subspaces of the Hardy space. Since the

Inspired by the work of Hedenmalm, Lindqvist and Seip, we consider different properties of dilations systems of a fixed function φ ∈ L 2 ( 0 , 1 ) . More precisely, we study when the system { φ ( n x ) } n is a Bessel sequence, a Riesz sequence,

Given two subsets A and B of the algebra of bounded linear operators on a Hilbert space H we denote by A B : = { AB : A ∈ A , B ∈ B } . The goal of this article is to describe A B if A and B denote classes of projections, partial isometries, posi
