Spectral analysis of Dirac operators on bounded domains.
(2022-07-07)This thesis is devoted to the spectral study of two types of perturbation of theDirac operator, which are singular from the point of view of scaling.In the first part of this thesis, we consider the coupling of the Dirac ... -
Statistical Modelling for Recurrent Events in Sports Injury Research with Applications to Football InjuryData.
(2024-02-16)Sports injuries stand as undesirable side effects of athletic participation, carrying serious consequencesfor athletes' health, their professional careers, and overall team performance. With the growing availability of ... -
Stochastic processes for anomalous diffusion
(2019-10-24)Con difusión anómala se hace referencia a procesos de difusión en los cuales el desplazamiento cuadrático medio (MSD) no es una función lineal de la variable tiempo (lo que se conoce como difusión normal). Cuando la relación ... -
Structural properties of hierarchically hyperbolic groups
(2020-11-12)Los temas de esta tesis se enmarcan en el área de la teoría geométrica de grupos, que es el estudio de grupos finitamente generados a través de la exploración de sus aspectos geométricos y topológicos. Más precisamente, ... -
Subgroups of direct products of limit groups over coherent right-angled Artin groups
(2022-07-08)During the last 40 years, a large body of work has been directed to study the connection betweenfiniteness properties of groups and their algebraic and algorithmic properties. One of the early results isdue to Baumslag and ... -
The forward problem for the electromagnetic Helmholtz equation
(2014-03-12)[EN]We consider the Helmholtz equation in Rd, d 3, with electric and magnetic potentials. The aim of this thesis is to study the direct problem of such an equation for potentials that decay at in nity, but also have ... -
The random diffusivity approach for diffusion in heterogeneous systems.
(2020-12-16)The two hallmark features of Brownian motion are the linear growth of the meansquared displacement (MSD) with diffusion coefficient D in d spatial dimensions, andthe Gaussian distribution of displacements. With the increasing ... -
The Schrödinger Equaton and Uncertainty Principles
(2020-09-02)The main task of this thesis is the analysis of the initial data u0 of Schrödinger’s initial value problem in order to determine certain properties of its dynamical evolution. First, we consider the elliptic Schrödinger ... -
Topics in Harmonic Analysis; commutators and directional singular integrals.
(2020-03-26)La tesis presentada viene dividida en dos partes: la primer parte está dedicada al estudio de losconmutadores y la segunda a los operadores maximales direccionales. Dentro de la teoría de losconmutadores nos enfocamos en ... -
Various results concerning homogenisation of nematic liquid crystals
(2022-10-17)In this tesis we present various results concerning homogenisation ofnematic liquid crystals: two of them are in perforated domains, while the other oneconcerns rates of convergence for boundary homogenisation. The first ... -
Varopoulos extensions of boundary functions in Lp and BMO in domains with Ahlforsregular boundaries and applications
(2023-11-29)This thesis focuses on the construnction of Varopoulos-type extensions of Lp and BMO boundary functions in rough domains. To be more specific, let Ω ⊂ Rn+1, n ≥ 1, be an open set with s-Ahlfors regular boundary ∂Ω, for ... -
Visibility recovery on images acquired in attenuating media. Application to underwater, fog, and mammographic imaging
(2015-12-17)When acquired in attenuating media, digital images of ten suffer from a particularly complex degradation that reduces their visual quality, hindering their suitability for further computational applications, or simply ...
