Application of the Stampacchia lemma to anisotropic degenerate elliptic equations

Journal of Innovative Applied Mathematics and Computational Sciences, 2023
In this paper, we prove the existence and regularity of solutions for a class of nonlinear anisotropic degenerate elliptic equations with the data f belonging to certain Marcinkiewicz spaces Mm(Ω) with m > 1.

Commutators of log-Dini-type parametric Marcinkiewicz operators on non-homogeneous metric measure spaces

Journal of Inequalities and Applications, 2021
Let ( X , d , μ ) $(\mathcal{X}, d, \mu )$ be a non-homogeneous metric measure space, which satisfies the geometrically doubling condition and the upper doubling condition.

New examples of K-monotone weighted Banach couples [PDF]

, 2012
Some new examples of K-monotone couples of the type (X, X(w)), where X is a symmetric space on [0, 1] and w is a weight on [0, 1], are presented. Based on the property of the w-decomposability of a symmetric space we show that, if a weight w changes ...

Noncommutative strong maximals and almost uniform convergence in several directions

Forum of Mathematics, Sigma, 2020
Our first result is a noncommutative form of the Jessen-Marcinkiewicz-Zygmund theorem for the maximal limit of multiparametric martingales or ergodic means.

Equidistribution of the Fekete points on the sphere [PDF]

, 2008
The Fekete points are the points that maximize a Vandermonde-type determinant that appears in the polynomial Lagrange interpolation formula. They are well suited points for interpolation formulas and numerical integration.

Marcinkiewicz–Zygmund Inequalities for Polynomials in Bergman and Hardy Spaces [PDF]

The Journal of Geometric Analysis, 2021
AbstractWe study the relationship between sampling sequences in infinite dimensional Hilbert spaces of analytic functions and Marcinkiewicz–Zygmund inequalities in subspaces of polynomials. We focus on the study of the Hardy space and the Bergman space in one variable because they provide two settings with a strikingly different behavior.

On Some Conditions for Strong Law of Large Numbers for Weighted Sums of END Random Variables under Sublinear Expectations

Discrete Dynamics in Nature and Society, 2019
In this article, we research some conditions for strong law of large numbers (SLLNs) for weighted sums of extended negatively dependent (END) random variables under sublinear expectation space.
