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 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 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 ... -
Adding user interactivity to FreeFem++ with EJS: From teaching to research
(2015-05-15)In this talk we propose the use of an authoring tool, Easy Java Simulations, to build interactive simulations for pdes where the computing kernel is FreeFem++. This tool allows to play with all the parameters of the pde ... -

All-regime Lagrangian-Remap numerical schemes for the gas dynamics equations. Applications to the large friction and low Mach coefficients
(2016-05-16)In this talk, we propose an all regime Lagrange-Projection like numerical scheme for the gas dynamics equations. By all regime, we mean that the numerical scheme is able to compute accurate approximate solutions with an ... -
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 variance of the Beurling transform
(2017-03-17)symptotic variance can be used to measure the boundary behaviour of conformal maps and Bloch functions. A formula due to McMullen connects it to the Hausdorff dimension expansion of limit sets for certain dynamical families ... -
Bergman projection induced by radial weight and Litlewood-Paley estimates
(2019-10-04)Se estudia la acotación de la proyección de Bergman entre espacios L^p y su relación con estimaciones de tipo Littlewood-Paley en términos de la derivadas sucesivas -
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 < ∞, ... -
Caracterización de la compacidad mediante la propiedad del punto fijo para aplicaciones continuas
(2016-03-15)Inspirados en un resultado de Klee [3] sobre la propiedad del punto fijo de conjuntos convexos en espacios lineales localmente convexos, probamos una caracterización de la compacidad de los espacios geodésicos mediante ... -
Catálisis de oxidación inspirada en metaloenzimas
(2015-12-01)La formación y la escisión del enlace O-O es posiblemente la reacción más importante en los organismos vivos. La rotura reductora del enlace O-O se lleva a cabo en el citocromo C oxidasa. [1] Esta reacción constituye el ... -

Cesàro-like operators acting on spaces of analytic functions
(Springer, 2022-03-17)Let D be the unit disc in C. If μ is a finite positive Borel measure on the interval [0, 1) and f is an analytic function in D, f(z)=∑∞n=0anzn (z∈D), we define Cμ(f)(z)=∑n=0∞μn(∑k=0nak)zn,z∈D, where, for n≥0, μn denotes ... -
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) ... -
Ciclicidad de polinomios en 2 variables
(2015-02-11)Sea $f$ una funcion de $H$, un espacio de Hilbert de funciones analiticas sobre un dominio fijado. Decimos que $f$ es ciclica si los polinomios multiplicados por $f$ forman un subespacio denso de $H$. Un teorema clasico ... -

Composition of Haar Paraproducts
(2014-12-03)Paraproducts are important operators in harmonic analysis and there are well known characterizations of when an individual paraproduct is bounded. An interesting question is to characterize when the composition of two, ...
