A Bayesian Solution to the Behrens-Fisher problem
Girón González-Torre, F. Javier; Castillo-Vázquez, Carmen
(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 ... -
Asymptotic properties of parameter estimates for random fields with tapered data.
Alomari, Huda Mohammed; Frías, María P.; Leonenko, Nikolai; Ruiz-Medina, María D.; Sakhno, Lyudmyla; Torres-Signes, Antoni[et al.] (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 ... -
Bergman projection on Lebesgue space Induced by doubling weight
Peláez-Márquez, José Ángel; De la Rosa, Elena; Rättyä, Jouni (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
Galanopoulos, Petros; Girela-Álvarez, Daniel; Merchán-Álvarez, Noel (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) ... -
Convergence in the Cesàro sense of ergodic operators associated with a flow.
We study the a.e. convergence ofthe Ceshro-(1 +c) ergodic averages and the a.e. existence in the Ceso-u sense ofthe ergodic Hilbert transform associated with a Cesobounded flow and < c < 0. -
COVID-19 mortality analysis from soft-data multivariate curve regression and machine learning.
Torres-Signes, Antoni; Frías, María P.; Ruiz-Medina, María D. (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 ... -
Fractional derivative description of the bloch space
Moreno, Álvaro Miguel; Peláez-Márquez, José Ángel; De la Rosa, Elena (Springer Nature, 2024-01-09)
We establish new characterizations of the Bloch space B which include descriptions in terms of classical fractional derivatives. Being precise, for an analytic function f (z) = E∞n=0 ^f(n)zn in the unit disc D, we define ... -
High-order fully well-balanced numerical methods for one-dimensional blood flow with discontinuous properties

In this paper, we are interested in the numerical study of the one-dimensional blood flow model with discontinuous mechanical and geometrical properties. We present the mathematical model together with its nondimensional ... -
High-order in-cell discontinuous reconstruction path-conservative methods for nonconservative hyperbolic systems–DR.MOOD method
Pimentel García, Ernesto; Castro-Díaz, Manuel Jesús; Chalons, Christophe; Parés-Madroñal, Carlos María (Wiley, 2024)
In this work, we develop a new framework to deal numerically with discontinuous solutions in nonconservative hyperbolic systems. First an extension of the MOOD methodology to nonconservative systems based on Taylor expansions ... -
Hilbert-type operator induced by radial weight on Hardyspaces
Merchán-Álvarez, Noel; Peláez-Márquez, José Ángel; De la Rosa, Elena (Springer Nature, 2023-09-19)
We consider the Hilbert-type operator defined by Hω(f)(z)=∫10f(t)(1z∫z0Bωt(u)du)ω(t)dt, where {Bωζ}ζ∈D are the reproducing kernels of the Bergman space A2ω induced by a radial weight ω in the unit disc D. We prove ... -

Caballero-Cárdenas, C; Castro-Díaz, Manuel Jesús; Morales-de-Luna, Tomás (Elsevier, 2022-12-25)
In this paper we consider the Lagrange-Projection technique in the framework of finite volume schemes applied to the shallow water system. We shall consider two versions of the scheme for the Lagrangian step: one fully ... -

Gómez Bueno, Irene; Boscarino, S; Castro-Díaz, Manuel Jesús; Parés-Madroñal, Carlos María; Russo, G (Elsevier, 2022-09-30)
The aim of this work is to design implicit and semi-implicit high-order well-balanced finite-volume numerical methods for 1D systems of balance laws. The strategy introduced by two of the authors in some previous papers ... -
Mixed weak-type inequalities in Euclidean spaces and in spaces of the homogeneous type
(Wiley, 2023-11-05)In this paper, we provide mixed weak-type inequalities generalizing previous results in an earlier work by Caldarelli and the second author and also in the spirit of earlier results by Lorente et al. One of the main novelties ... -
