Some new weighted weak-type iterated and bilinear modified Hardy inequalities
(Springer Nature, 2024-03-02)We characterize the good weights for some weighted weak-type iterated and bilinear modified Hardy inequalities to hold. -
Point pattern analysis and classification on compact two-point homogeneous spaces evolving time.
(2023-02-14)This paper introduces a new modeling framework for the statistical analysis of point patterns on a manifold Md; defined by a connected and compact two-point homogeneous space, including the special case of the sphere. The ... -
COVID-19 mortality analysis from soft-data multivariate curve regression and machine learning.
(2021-03-19)A multiple objective space-time forecasting approach is presented involving cyclical curve log-regression, and multivariate time series spatial residual correlation analysis. Specifically, the mean quadratic loss function ... -
A Bayesian Functional Methodology for Dengue Risk Mapping in Latin America and the Caribbean
(2021)Dengue fever has become one of the most outstanding infectious diseases in the world. Besides, the incidence and prevalence of dengue are increasing in the endemic areas of the tropical and subtropical regions. Space and ... -
A spatial functional count model for heterogeneity analysis in time
(2021)A spatial curve dynamical model framework is adopted for functional prediction of counts in a spatiotemporal logGaussian Cox process model. Our spatial functional estimation approach handles both wavelet-based heterogeneity ... -
Spatial Cox processes in an infinite-dimensional framework
(2022)We introduce a new class of spatial Cox processes driven by a Hilbert-valued random log-intensity. We adopt a parametric framework in the spectral domain, to estimate its spatial functional correlation structure. Specifically, ... -
Singular integrals in the Cesàro sense
(Springer, Birkhäuser Verlag, 2000)The existence of the singular integral ∫K(x, y)f(y)dy associated to a Calderón-Zygmund kernel where the integral is understood in the principal value sense TF(x)=limε→0+∫|x−y|>εK(x, y)f(y)dy has been well studied. In this ... -
Weighted inequalities for commutators of fractional integrals on spaces of homogeneous type.
(Elsevier, 2006)Let 0 <γ< 1, b be a BMO function and Im γ,b the commutator of order m for the fractional integral. We prove two type of weighted Lp inequalities for Im γ,b in the context of the spaces of homogeneous type. The first one ... -
A new proof of the characterization of the weighted Hardy inequality
(Cambridge University Press, 2005)Maz'ja and Sinnamon proved a characterization of the boundedness of the Hardy operator from Lp(v) into Lq(w) in the case 0 < q < p, 1 < p < ∞. We present here a new simple proof of the sufficiency part of that result. -
Multiresolution approximations and wavelet bases of weighted Lp spaces
(Springer, Birkhäuser Verlag, 2003)We study boundedness and convergence on L p(R n,dμ) of the projection operators P j given by MRA structures with non-necessarily compactly supported scaling function. As a consequence, we prove that if w is a locally ...
