Mixed Martingale Hardy Spaces [PDF]

open access: yesThe Journal of Geometric Analysis, 2020
AbstractIn this paper, we consider the martingale Hardy spaces defined with the help of the mixed $$L_{\overrightarrow{p}}$$ L p → -norm. Five mixed martingale Hardy spaces will be investigated:

Martingale Morrey-Hardy and Campanato-Hardy Spaces [PDF]

open access: yesJournal of Function Spaces and Applications, 2013
We introduce generalized Morrey-Campanato spaces of martingales, which generalize both martingale Lipschitz spaces introduced by Weisz (1990) and martingale Morrey-Campanato spaces introduced in 2012. We also introduce generalized Morrey-Hardy and Campanato-Hardy spaces of martingales and study Burkholder-type equivalence.

Some new results and inequalities for subsequences of Nörlund logarithmic means of Walsh–Fourier series

open access: yesJournal of Inequalities and Applications, 2022
We prove that there exists a martingale f ∈ H p $f\in H_{p} $ such that the subsequence { L 2 n f } $\{L_{2^{n}}f \}$ of Nörlund logarithmic means with respect to the Walsh system are not bounded from the martingale Hardy spaces H p $H_{p}$ to the space ...

( H p − L p ) $(H_{p}-L_{p})$ -Type inequalities for subsequences of Nörlund means of Walsh–Fourier series

open access: yesJournal of Inequalities and Applications, 2023
We investigate the subsequence { t 2 n f } $\{t_{2^{n}}f \}$ of Nörlund means with respect to the Walsh system generated by nonincreasing and convex sequences.

Weak Orlicz–Hardy martingale spaces [PDF]

open access: yesInternational Journal of Mathematics, 2015
In this paper, several weak Orlicz–Hardy martingale spaces associated with concave functions are introduced, and some weak atomic decomposition theorems for them are established. With the help of weak atomic decompositions, a sufficient condition for a sublinear operator defined on the weak Orlicz–Hardy martingale spaces to be bounded is given ...

Some weak type inequalities and almost everywhere convergence of Vilenkin–Nörlund means

open access: yesJournal of Inequalities and Applications, 2023
We prove and discuss some new weak type ( 1 , 1 ) $(1,1 ) $ inequalities of maximal operators of Vilenkin–Nörlund means generated by monotone coefficients. Moreover, we use these results to prove a.e. convergence of such Vilenkin–Nörlund means.

An equivalent quasinorm for the Lipschitz space of noncommutative martingales

open access: yesOpen Mathematics, 2020
In this paper, an equivalent quasinorm for the Lipschitz space of noncommutative martingales is presented. As an application, we obtain the duality theorem between the noncommutative martingale Hardy space hpc(ℳ){h}_{p}^{c}( {\mathcal M} ) (resp.

A Remark on Atomic Decompositions of Martingale Hardy’s Spaces [PDF]

open access: yesThe Journal of Geometric Analysis, 2020
AbstractWe prove theorems and exhibit a counterexample concerning an atomic decomposition of martingale $${{\mathbb {H}}^1}$$ H 1 with atoms satisfying simultaneous cancellation condition (3).
