Anisotropic Hardy spaces and wavelets
In this paper, motivated in part by the role of discrete groups of dilations in wavelet theory, we introduce and investigate the anisotropic Hardy spaces associated with very general discrete groups of dilations.

Hardy spaces, BMO, and boundary value problems for the Laplacian on a smooth domain in ^{}
We study two different local Hp spaces, 0 < p ≤ 1, on a smooth domain in Rn, by means of maximal functions and atomic decomposition. We prove the regularity in these spaces, as well as in the corresponding dual BMO spaces, of the Dirichlet and Neumann ...

Analytic Variable Exponent Hardy Spaces [PDF]
We introduce a variable exponent version of the Hardy space of analytic functions on the unit disk, we show some properties of the space, and give an example of a variable exponent $p(\cdot)$ that satisfies the $\log$-H\"older condition such that $H^{p(\cdot)}\neq H^q$ for any constant exponent $1

Variational characterizations of weighted Hardy spaces and weighted $BMO$ spaces [PDF]
This paper obtains new characterizations of weighted Hardy spaces and certain weighted $BMO$ type spaces via the boundedness of variation operators associated with approximate identities and their commutators, respectively.

On the restricted summability of the multi-dimensional Vilenkin-Cesàro means
The properties of the maximal operator of the (C,α) -means (α = (α1, . . . ,αd) ) of the multi-dimensional Vilenkin-Fourier series are discussed, where the set of indices is inside a cone-like set.

Modular Lattice for $C_{o}$-Operators [PDF]
We study modularity of the lattice Lat $(T)$ of closed invariant subspaces for a $C_0$-operator $T$ and find a condition such that Lat $(T)$ is a modular. Furthermore, we provide a quasiaffinity preserving modularity.

Pointwise characterizations of Hardy-Sobolev functions [PDF]
We establish simple pointwise characterizations of functions in the Hardy-Sobolev spaces within the range n/(n+1)
A Shift Operator on L(H^2) [PDF]
We give definitions and some properties of the shift operator S_{L(H^2)} and multiplication operator on L(H^2). In addition, we obtain some properties of the commutant of the shift operator S_{L(H^2)} and characterize S_{L(H^2)}-invariant subspaces.
