Invariance of a shift-invariant space
(Birkhauser Boston Inc, 2010-01)
A shift-invariant space is a space of functions that is invariant under integer translations. Such spaces are often used as models for spaces of signals and images in mathematical and engineering applications. This paper ...

Borel and Hausdorff hierarchies in topological spaces of Choquet games and their effectivization
(Cambridge University Press, 2015-10)
What parts of the classical descriptive set theory done in Polish spaces still hold for more general topological spaces, possibly T0 or T1, but not T2 (i.e. not Hausdorff)? This question has been addressed by Selivanov in ...
Invariance of a Shift-Invariant Space in Several Variables
(Springer, 2011-12)
In this article we study invariance properties of shift-invariant spaces in higher dimensions. We state and prove several necessary and sufficient conditions for a shift-invariant space to be invariant under a given closed ...
Haar type bases in lorentz spaces via extrapolation
(Unión Matemática Argentina, 2012-06)
In this note we consider Haar type systems as unconditional bases for Lorentz spaces defined on spaces of homogeneous type. We also give characterizations of these spaces in terms of the Haar coefficients. The basic tools ...
A stronger reformulation of Webb's conjecture in terms of finite topological spaces
(Academic Press Inc Elsevier Science, 2019-06)
We investigate a stronger formulation of Webb's conjecture on the contractibility of the orbit space of the p-subgroup complexes in terms of finite topological spaces. The original conjecture, which was first proved by ...
Weighted inequalities for integral operators on Lebesgue and BMOγ(ω) spaces
(Universidad de Barcelona, 2019-01-16)
We characterize the power weights ω for which the fractional type operator Tα , β is bounded from Lp(ωp) into Lq(ωq) for 1 < p< n/ (n- (α+ β)) and 1 / q= 1 / p- (n- (α+ β)) / n. If n/ (n- (α+ β)) ≤ p< n/ (n- (α+ β) - 1) + ...
Neuromodeling of microwave circuits exploiting space mapping technology

On operator ideals defined by a reflexive Orlicz sequence space
(Departamento de Matematicas, Universidad Catolica del Norte, 2006-01-01)
Classical theory of tensornorms and operator ideals studies mainly those defined by means of sequence spaces lp. Considering Orlicz sequence spaces as natural generalization of lp spaces, in a previous paper [12] an Orlicz ...
