Dominación sparse para conmutadores y estimaciones cuantitativas
(2018-02-07)Dada una funci ́on localmente integrable y un operador lineal T definimos el commutator [b, T ] como [b, T ]f (x) = b(x)T f (x) − T (bf )(x). En esta charla presentaremos resultados de dominación sparse para conmutadores ... -
One-sided Cp estimates via M# function.
Lorente-Domínguez, María
; Martin-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 ... -
Quantitative John–Nirenberg inequalities at different scales
Martínez-Perales, Javier Cecilio; Rela, Ezequiel; Rivera Ríos, Israel P. (Springer, 2022-06-07)
Given a family Z = { · Z Q } of norms or quasi-norms with uniformly bounded triangle inequality constants, where each Q is a cube in Rn, we provide an abstract estimate of the form f − fQ,μZ Q ≤ c(μ)ψ(Z) f BMO(dμ) for ... -
Some quantitative one-sided weighted estimates
Lorente-Domínguez, María; Martin-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 ...
