(2017-05-17)This presentation provides a survey of some recent results related to efficient numerical methods for the numerical solution of a class of convection-diffusion systems that arise as one-dimensional models of the flow of ... -
On geophysical applications of two-layer and two-phase shallow models
(2018-04-23)The main objective of this talk is to present some geophysical applications that can be studied with two-layer or two-phase shallow models. Namely, applications on avalanches and sediment transport problems. Firstly, several ... -
On the radicality property for spaces of symbols of bounded Volterra operators
Cascante, Carme; Fàbrega, Joan; Pascuas, Daniel; Peláez-Márquez, José Ángel
(Elsevier, 2024-09)
In [1] it is shown that the Bloch space in the unit disc has the following radicality property: if an analytic function g satisfies that , then , for all . Since coincides with the space of analytic symbols g such that the ... -
On the sharpness of some quantitative Muckenhoupt-Wheeden inequalities.
(Académie des sciences, 2024). In the recent work [Cruz-Uribe et al. (2021)] it was obtained that |{x ∈ R d : w(x)|G(f w−1 )(x)| > α}| ≲ [w] 2 A1 α Z Rd |f |dx both in the matrix and scalar settings, where G is either the Hardy–Littlewood ... -
On two weight estimates for iterated commutators.
(Elsevier, 2021)In this paper we extend the bump conjecture and a particular case of the separated bump conjecture with logarithmic bumps to iterated commutators . Our results are new even for the first order commutator . A new bump ... -
Ondículas: historia, teoría y aplicación
(2019-10-02)La Academia Noruega de las Ciencias y las Letras concedió,el 23 de mayo de 2017, el premio Abel al matemático francés Yves Meyer, «por su importante papel en el desarrollo de la teoría matemática de las ondículas», según ... -
One-sided Cp estimates via M# function.
Lorente-Domínguez, María; Martín-Reyes, Francisco Javier; Rivera Ríos, Israel P. (Cambridge, 2022-07-04)
We recall that w ∈ C+p if there exist " > 0 and C > 0 such that for any a < b < c with c − b < b − a and any measurable set E ⊂ (a, b), the following holds. This condition was introduced by Riveros and de la Torre as a ... -
Operadores de superposición actuando entre espacios de funciones analíticas
(UMA Editorial, 2021-02-23)En esta Tesis se estudia la acción de operadores de superposición y operadores de superposición ponderados entre distintos espacios de funciones holomorfas en el disco unidad del plano complejo. -
Operators induced by radial measures acting on the Dirichlet space
Galanopoulos, Petros; Girela-Álvarez, Daniel; Mas, Alejandro; Merchán-Álvarez, Noel (Springer, 2023)
Let D be the unit disc in the complex plane. Given a positive finite Borel measure μ on the radius [0, 1), we let μn denote the n-th moment of μ and we deal with the action on spaces of analytic functions in D of the ... -
Optimalidad en la conjetura débil de Muckenhoupt-Wheeden
(2018-03-06)En el año 2009 conjuntamente con A. Lerner y C. P\'erez probamos que la dependencia en relación a la constante $[w]_A_1$ de un peso $w$ en el tipo débil (1,1) de la cualquier operador de Calderón-Zygmund se puede controlar ... -
Orbital debris and the market for satellites
Bongers-Chicano, Aneli María; Torres-Chacón, José Luis (Elsevier, 2023)
This paper studies the economic consequences of orbital debris for commercial outer-space activities. Spacecraft launches and other outer-space human activities produce pollution (i.e., orbital debris), which represent a ... -
