, 1998
Superalgebras including generators having spins up to two and realisable as tangent vector fields on Lorentz covariant generalised superspaces are considered.

Atomic decompositions of Lorentz martingale spaces and applications

Journal of Function Spaces and Applications, 2009
In the paper we present three atomic decomposition theorems of Lorentz martingale spaces. With the help of atomic decomposition we obtain a sufficient condition for sublinear operator defined on Lorentz martingale spaces to be bounded.

A Note on Multiplication and Composition Operators in Lorentz Spaces

Journal of Function Spaces and Applications, 2012
we revisit the Lorentz spaces 𝐿(𝑝,𝑞) for 𝑝>1,𝑞>0 defined by G. G. Lorentz in the nineteen fifties and we show how the atomic decomposition of the spaces 𝐿(𝑝,1) obtained by De Souza in 2010 can be used to characterize the multiplication and composition ...

Noncommutative spaces, the quantum of time and the Lorentz symmetry [PDF]

, 2007
We introduce three space-times that are discrete in time and compatible with the Lorentz symmetry. We show that these spaces are no commutative, with commutation relations similar to the relations of the Snyder and Yang spaces.

Triebel–Lizorkin–Lorentz Spaces and the Navier–Stokes Equations [PDF]

Zeitschrift für Analysis und ihre Anwendungen, 2017
We derive basic properties of Triebel-Lizorkin-Lorentz spaces important in the treatment of PDE. For instance, we prove Triebel-Lizorkin-Lorentz spaces to be of class $\mathcal{HT}$, to have property $(\alpha)$, and to admit a multiplier result of ...

Atomic Decomposition of Weighted Lorentz Spaces and Operators

Journal of Function Spaces, 2014
We obtain an atomic decomposition of weighted Lorentz spaces for a class of weights satisfying the Δ2 condition. Consequently, we study operators such as the multiplication and composition operators and also provide Hölder’s-type and duality-Riesz type ...

On radial Fourier multipliers and almost everywhere convergence [PDF]

, 2014
We study a.e. convergence on $L^p$, and Lorentz spaces $L^{p,q}$, $p>\tfrac{2d}{d-1}$, for variants of Riesz means at the critical index $d(\tfrac 12-\tfrac 1p)-\tfrac12$.

Littlewood-Paley Characterizations of Anisotropic Hardy-Lorentz Spaces [PDF]

, 2016
Let $p\in(0,1]$, $q\in(0,\infty]$ and $A$ be a general expansive matrix on $\mathbb{R}^n$. Let $H^{p,q}_A(\mathbb{R}^n)$ be the anisotropic Hardy-Lorentz spaces associated with $A$ defined via the non-tangential grand maximal function.

The Monotonicity of Orlicz-Lorentz Sequence Spaces Equipped with the F-norm

Journal of Harbin University of Science and Technology
We introduce a new F-normed spaces, namely Orlicz-Lorentz spaces equipped with the Mazur-Orlicz F-norm, and study some properties, prove that Orlicz-Lorentz spaces equipped with the F-norm are complete F-spaces.
