Implicit and implicit-explicit Lagrange-projection finite volume schemes exactly well-balanced for 1D shallow water system
(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 ... -
Implicit and semi-implicit well-balanced finite-volume methods for systems of balance laws
(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 ... -
In-cell discontinuous reconstruction path-conservative methods for non conservative hyperbolic systems - Second-order extension
(Elsevier, 2022-06-15)We are interested in the numerical approximation of discontinuous solutions in non conservative hyperbolic systems. An extension to second-order of a new strategy based on in-cell discontinuous reconstructions to deal with ... -
Integral Operators Induced by Symbols with Non-negative Maclaurin Coefficients Mapping into H∞
(Springer, 2022-02-20)For analytic functions g on the unit disk with non-negative Maclaurin coefficients, we describe the boundedness and compactness of the integral operator Tg( f )(z) = z 0 f (ζ )g(ζ ) dζ from a space X of analytic functions ... -

Iterated nonexpansive mappings
(2018-05-03)We present a further study on fixed point theory for the so called iterated nonexpansive mappings, that is, mappings which are nonexpansive along the orbits. They are a direct generalization of the contraction type maps ... -
Log-Gaussian Cox Process in Infinite-Dimensional Spaces.
(American Mathematical Society, 2018)This paper introduces new results on doubly stochastic Poisson processes, with log-Gaussian Hilbert-valued random intensity (LGHRI), defined from the Ornstein-Uhlenbeck process (O-U process) in Hilbert spaces. Sufficient ... -
Mathematical and numerical modelling of dispersive water waves
(UMA Editorial, 2018-11-14)En esta tesis doctoral se expone en primer lugar una visión general del modelado de ondas dispersivas para la simulación de procesos tsunami-génicos. Se deduce un nuevo sistema bicapa con propiedades de dispersión mejoradas ... -
Mathematical models in Developmental Biology
(2016-11-29)We will introduce some of the mathematical modeling tools that have been introduced in the field of Developmental Biology, focusing in specific problems in embryogenesis. The use of multiscale models based on a combination ... -
Métodos variacionales para problemas no variacionales
(2016-11-11)A partir de algunos resultados clásicos sobre problemas variacionales regulares y sus EDPs subyacentes, pretendemos tratar la situación más general de un problema no variacional sin una energía natural pero reteniendo las ... -
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 ... -
Modelado y simulación de procesos sedimentarios en aguas someras
(UMA Editorial, 2021-05-12)En esta tesis se deduce un modelo matemático de tipo aguas someras para el transporte de sedimentos sin hacer uso de la hipótesis de Boussinesq. Dicho modelo es resuelto de forma numerica mediante un esquema robusto y ... -

(CEDYA 2013/IMAC/Universitat Jaume I, 2013)Los modelos NPZ (siglas para Nutrientes-Fitoplancton-Zooplancton en inglés) son comúnmente utilizados en estudios de biología marina. Este tipo de modelos utiliza un conjunto de ecuaciones diferenciales muy sencillo para ... -
Multidimensional approximate Riemann solvers for hyperbolic systems

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 ... -
Networks of hyperbolic balance laws
(2017-11-17)Models with networks of hyperbolic balance laws are currently used for several applications, e.g. river flows, the human circulatory system, gas pipelines or road networks. These motivations triggered a constant development ... -
