Comportement extrémal des copules diagonales et de Bertino

open access: yesComptes 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 the Hardy-Littlewood maximal operator on block decreasing functions [PDF]

open access: yes, 2009
We study the Hardy-Littlewood maximal operator defined via an unconditional norm, acting on block decreasing functions. We show that the uncentered maximal operator maps block decreasing functions of special bounded variation to functions with integrable

Maximal regular boundary value problems in Banach-valued function spaces and applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The nonlocal boundary value problems for differential operator equations of second order with dependent coefficients are studied. The principal parts of the differential operators generated by these problems are non-selfadjoint.

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

open access: yesJournal 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.

Each regular code is included in a maximal regular code [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 1986
It is proved here that each regular code is included in a maximal regular code. Other concepts of codes related to maximality are involved. The main result solves a long standing open problem in the theory of formal languages and combinatorial semigroup theory.

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

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

On Surfaces of Maximal Sectional Regularity

open access: yesTaiwanese Journal of Mathematics, 2017
We study projective surfaces $X \subset \mathbb{P}^r$ (with $r \geq 5$) of maximal sectional regularity and degree $d > r$, hence surfaces for which the Castelnuovo-Mumford regularity $\reg(\mathcal{C})$ of a general hyperplane section curve $\mathcal{C} = X \cap \mathbb{P}^{r-1}$ takes the maximally possible value $d-r+3$. We use the classification
