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 Bayesian Solution to the Behrens-Fisher problem
(Springer, 2021-07)A simple solution to the Behrens–Fisher problem based on Bayes factors is presented, and its relation with the Behrens–Fisher distribution is explored. The construction of the Bayes factor is based on a simple hierarchical ... -
A class of multilinear bounded oscillation operators on measure spaces and applications.
(Springer Nature, 2023)recent years, dyadic analysis has attracted a lot of attention due to the conjecture. It has been well understood that in the Euclidean setting, Calderón–Zygmund operators can be pointwise controlled by a finite number ... -
A Class of Well-Balanced Algorithms for Relativistic Fluids on a Schwarzschild Background
(SPRINGER, 2021-08-16)For the evolution of a compressible fluid in spherical symmetry on a Schwarzschild curved background, we design a class of well-balanced numerical algorithms up to third-order accuracy. We treat both the relativistic ... -
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. -
A novel embedded min-max approach for feature selection in nonlinear Support Vector Machine classification
(Elsevier, 2021)In recent years, feature selection has become a challenging problem in several machine learning fields, such as classification problems. Support Vector Machine (SVM) is a well-known technique applied in classification ... -
A semi-implicit fully exactly well-balanced relaxation scheme for the shallow water system.
(SIAM, 2024)This article focuses on the design of semi-implicit schemes that are fully well-balanced for the one-dimensional shallow water equations, that is, schemes that preserve all smooth steady states of the system and not just ... -
A sparse approach to mixed weak type inequalities.
(Springer Nature, 2019-12-10)Abstract. In this paper we provide some quantitative mixed weak-type estimates assuming conditions that imply that uv ∈ A∞ for Calder´on-Zygmund operators, rough singular integrals and commutators. The main novelty of ... -
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 ... -
An Arbitrary High Order Well-Balanced ADER-DG Numerical Scheme for the Multilayer Shallow-Water Model with Variable Density
(Springer, 2021-12-17)In this work, we present a novel numerical discretization of a variable pressure multilayer shallow water model. The model can be written as a hyperbolic PDE system and allows the simulation of density driven gravity ... -
Asymptotic properties of parameter estimates for random fields with tapered data.
(Institute of Mathematical Statistics, 2017)In this paper we present novel results on the asymptotic behavior of the so-called Ibragimov minimum contrast estimates. The case of tapered data for various models of Gaussian random fields is investigated. The CLT for ... -
Automatic feature scaling and selection for support vector machine classification with functional data.
(Springer Nature, 2020)Functional Data Analysis (FDA) has become a very important field in recent years due to its wide range of applications. However, there are several real-life applications in which hybrid functional data appear, i.e., data ... -
Bergman projection and BMO in hyperbolic metric: improvement of classical result.
(Springer Nature, 2023)The Bergman projection $P_\alpha$, induced by a standard radial weight, is bounded and onto from $L^\infty$ to the Bloch space $\mathcal{B}$. However, $P_\alpha: L^\infty\to \mathcal{B}$ is not a projection. This fact can ... -
Bergman projection induced by radial weight acting on growth spaces
(Springer, 2024)Let ω be a radial weight on the unit disc of the complex plane D and denote by ω(r) = 1 r ω(s) ds the tail integrals. A radial weight ω belongs to the class D if satisfies the upper doubling condition sup 0<r< ∞. If ν ... -
Bergman projection induced by radial weight.
(Elsevier, 2021)We establish characterizations of the radial weights $\omega$ on the unit disc such that the Bergman projection $P_\omega$, induced by $\omega$, is bounded and/or acts surjectively from $L^\infty$ to the Bloch space ... -
Bergman projection on Lebesgue space Induced by doubling weight
(Springer Nature, 2023-11-28)Let ω and ν be radial weights on the unit disc of the complex plane, and denote σ = ωp′ ν− p′ p and ωx = ∫ 1 0 sxω(s) ds for all 1 ≤ x < ∞. Consider the one-weight inequality ‖Pω (f )‖Lp ν ≤ C‖f ‖Lp ν , 1 < p < ∞, ... -

Cesàro-type operators associated with Borel measures on the unit disc acting on some Hilbert spaces of analytic functions
(Elsevier, 2023)Given a complex Borel measure μon the unit disc D={z∈C:|z| <1}, we consider the Cesàro-type operator Cμdefined on the space Hol(D)of all analytic functions in Das follows: If f∈Hol(D), f(z) = ∞n=0anzn(z∈D), then Cμ(f)(z) ... -
