Sawyer’s problem and related open question for one-sided maximal functions
(2018-03-06)In this talk, I will introduce the Sawyer's conjecture, which was proposed by Sawyer in 1980s. Then in 2005, Cruz-Uribe, Martell and Pérez finally solved this conjecture, they also proposed a new conjecture, which can ... -
Sharp A1 weighted estimates for vector valued operators.
(Springer Nature, 2021)Given 1 ≤ q < p < ∞, quantitative weighted L p estimates, in terms of Aq weights, for vector-valued maximal functions, Calderón–Zygmund operators, commutators, and maximal rough singular integrals are obtained. The results ... -
A sharp interface approach for compressible multiphase flow
(2019-07-04)The numerical simulation of compressible multiphase flow is a difficult task due to the close connection of thermodynamics and fluid dynamics. Our approach is based on a sharp interface treatment. The two phases are coupled ... -
Singular integrals in the Cesàro sense
Bernardis-Medici, Ana Lucía
; Martín-Reyes, Francisco Javier (Springer, Birkhäuser Verlag, 2000)
The existence of the singular integral ∫K(x, y)f(y)dy associated to a Calderón-Zygmund kernel where the integral is understood in the principal value sense TF(x)=limε→0+∫|x−y|>εK(x, y)f(y)dy has been well studied. In this ... -
Some new weighted weak-type iterated and bilinear modified Hardy inequalities
García García, V.; Ortega-Salvador, Pedro (Springer Nature, 2024-03-02)
We characterize the good weights for some weighted weak-type iterated and bilinear modified Hardy inequalities to hold. -
Some quantitative one-sided weighted estimates
Lorente-Domínguez, María; Martín-Reyes, Francisco Javier; Rivera Ríos, Israel P. (Elsevier, 2022-12-20)
We show a link between affine differential geometry and null submanifolds in a semi-Riemannian manifold via statistical structures. Once a rigging for a null submanifold is fixed, we can construct a semi-Riemannian metric ... -
Spaces of analytic functions and operators between them
Merchán-Álvarez, Noel (UMA Editorial, 2018-06-26)
Esta tesis está dedicada al estudio de ciertos operadores actuando en espacios de funciones analíticas en el disco unidad. El Capítulo 2 está dedicado al estudio de los operadores H_μ e I_μ en distintos espacios de ... -
Spatial Cox processes in an infinite-dimensional framework
We introduce a new class of spatial Cox processes driven by a Hilbert-valued random log-intensity. We adopt a parametric framework in the spectral domain, to estimate its spatial functional correlation structure. Specifically, ... -
Statistical properties of partially observed integrated functional depths
(Springer, 2024)Integrated functional depths (IFDs) present a versatile toolbox of methods introducing notions of ordering, quantiles, and rankings into a functional data analysis context. They provide fundamental tools for nonparametric ... -
The 2-weights problem for the Bergman projection and Sarason conjecture.
(2014-09-24)In the early 90's, D. Sarason posed conjectures on the characterization of the boundedness of Toeplitz products on Hardy and Bergman spaces (3). The Hardy space case attracted much attention because of its close relation ... -
The Kolmogorov Law of turbulence: what can rigorously be proved?
(2015-05-15)We define a mathematical framework in which we can specify the Reynolds decomposition and the correlation tensors of an incompressible locally homogeneous and isotropic turbulent flow. After having fixed the technical ... -
The Puerto Rico Tsunami Program after the 2004 Tsunami: Hazard and Vulnerability Assessment, Public Outreach and the Tsunami-Ready Program for Coastal Towns
(2014-06-10)Prior to the 2004 Indian Ocean tsunami the Caribbean island of Puerto Rico had implemented the Puerto Rico Tsunami Warning and Mitigation Program, with a grant from the USA’s FEMA. This program ended in 2003. For several ... -
Tight and Compact Sample Average Approximation for Joint Chance-Constrained Problems with Applications to Optimal Power Flow.
Porras, Álvaro; Domínguez Sánchez, Concepción; Morales-González, Juan Miguel; Pineda-Morente, Salvador (INFORMS, 2023-08-02)
In this paper, we tackle the resolution of chance-constrained problems reformulated via sample average approximation. The resulting data-driven deterministic reformulation takes the form of a large-scale mixed-integer ... -
Towards general purpose LES model of injection and atomization
(2015-05-15)Injection and atomization of liquid is widely used in many industrial and domestic applications such as, fuel injection in engines or burners, spray painting, medical sprays, spray drying, etc. Various approaches are ... -
Towards large scale unfitted adaptive finite element simulations
(2018-04-23)The use of unfitted finite element methods (FEMs) is an appealing approach for different reasons. They are interesting in coupled problems or to avoid the generation of body-fitted meshes. One of the bottlenecks of the ... -
Tsunami-HySEA model validation for tsunami current predictions
Macías-Sánchez, Jorge (European Geophysical Union, 2016)
Model ability to compute and predict tsunami flow velocities is of importance in risk assessment and hazard mitigation. Substantial damage can be produced by high velocity flows, particularly in harbors and bays, even when ... -
Two weight norm inequalities for fractional integrals and commutators
(2014-09-17)In this course we will survey recent work on two weight norm inequalities for the fractional integral operator and its commutator with BMO functions. We are interested in finding sufficient (and necessary and sufficient) ...
