Comportement extrémal des copules diagonales et de Bertino

Comptes Rendus. Mathématique, 2021
The maximal attractors of bivariate diagonal and Bertino copulas are determined under suitable regularity conditions. Some consequences of these facts are drawn, namely bounds on the maximal attractor of a symmetric copula with a given diagonal section ...

Regularity of Commutators of the One-Sided Hardy-Littlewood Maximal Functions

Journal of Function Spaces, 2020
In this paper, the regularity properties of two classes of commutators of the one-sided Hardy-Littlewood maximal functions and their fractional variants are investigated.

On the regularity of maximal operators [PDF]

, 2008
We study the regularity of the bilinear maximal operator when applied to Sobolev functions, proving that it maps $W^{1,p}(\mathbb{R}) \times W^{1,q}(\mathbb{R}) \to W^{1,r}(\mathbb{R})$ with $1 1$.

The Maximal Regularity of Nonlocal Parabolic Monge–Ampère Equations and Its Monotonicity in the Whole Space

Axioms
The Monge–Ampère operator, as a nonlinear operator embedded in parabolic differential equations, complicates the demonstration of maximal regularity for these equations.

A characterization of regular maximal ideals [PDF]

Pacific Journal of Mathematics, 1969
We show that if A is generated by a single element then a closed subspace M of codimension one in A and satisfying (1) is a regular maximal ideal and we show by an example that this result may fail for an algebra which is generated two elements. We have results related to the above, which can be applied to Lι(G), where G is a locally compact abelian ...

Maximal regularity for non-autonomous Robin boundary conditions

, 2015
We consider a non-autonomous Cauchy problem involving linear operators associated with time-dependent forms $a(t;.,.):V\times V\to {\mathbb{C}}$ where $V$ and $H$ are Hilbert spaces such that $V$ is continuously embedded in $H$.

Evolution Equations governed by Lipschitz Continuous Non-autonomous Forms [PDF]

, 2014
We prove $L^2$-maximal regularity of linear non-autonomous evolutionary Cauchy problem \begin{equation}\label{eq00}\nonumber \dot{u} (t)+A(t)u(t)=f(t) \hbox{ for }\ \hbox{a.e.

Endpoint Sobolev regularity of bilinear maximal commutators

AIMS Mathematics
In this paper our objective of investigation was the endpoint Sobolev regularity of the bilinear maximal commutator \begin{document}$ \mathfrak{M}_{b, \alpha}(f, g)(x) = \sup\limits_{r>0}\frac{1}{(2r)^{1-\alpha}}\int_{-r}^{r}|(b(x)-b(x+y))f(x+y)g(x-y)|

ОЦЕНКА МАКСИМАЛЬНОЙ РЕГУЛЯРНОСТИ ДЛЯ ДИФФЕРЕНЦИАЛЬНОГО УРАВНЕНИЯ С КОЛЕБЛЮЩИМИСЯ КОЭФФИЦИЕНТАМИ

Вестник КазНУ. Серия математика, механика, информатика, 2021
В работе рассматривается дифференциальное уравнение второго порядка с неограниченными коэффициентами. Получены достаточные условия суммируемости с весом решения и его производных вплоть до второго порядка.

Maximal Solutions of Sparse Analysis Regularization [PDF]

Journal of Optimization Theory and Applications, 2018
This paper deals with the non-uniqueness of the solutions of an analysis-Lasso regularization. Most of previous works in this area is concerned with the case where the solution set is a singleton, or to derive guarantees to enforce uniqueness. Our main contribution consists in providing a geometrical interpretation of a solution with a maximal D ...
