Hardy spaces associated with ball quasi‐Banach function spaces on spaces of homogeneous type: Characterizations of maximal functions, decompositions, and dual spaces [PDF]
Mathematische Nachrichten, 2021 Let (X,ρ,μ)$({\mathcal {X}},\rho ,\mu )$ be a space of homogeneous type in the sense of Coifman and Weiss, and let Y(X)$Y({\mathcal {X}})$ be a ball quasi‐Banach function space on X${\mathcal {X}}$ , which supports both a Fefferman–Stein vector‐valued ...

Maximal restriction estimates and the maximal function of the Fourier transform [PDF]
Proceedings of the American Mathematical Society, 2018 We prove a maximal restriction inequality for the Fourier transform, providing an answer to a question left open by M\"uller, Ricci and Wright. Our methods are similar to the ones in their article, with the addition of a suitable trick to help us ...

Maximal function characterizations for new local Hardy-type spaces on spaces of homogeneous type [PDF]
Transactions of the American Mathematical Society, 2016 Let X X be a space of homogeneous type and let L \mathfrak {L} be a nonnegative self-adjoint operator on L 2 ( X ) L^2(X) enjoying Gaussian estimates. The main aim of this paper is twofold. Firstly, we prove (

Coulomb blockade in two island systems with highly conductive junctions [PDF]
, 2004 We report measurements on single-electron pumps, consisting of two metallic islands formed by three tunnel junctions in series. We focus on the linear-response conductance as a function of gate voltage and temperature of three samples with varying system

Some estimates for commutators of the fractional maximal function on stratified Lie groups
Journal of Inequalities and Applications, 2023 In this paper, the main aim is to consider the boundedness of the nonlinear commutator [ b , M α ] $[b, M_{\alpha}]$ and the maximal commutator M α , b $M_{\alpha ,b}$ on the Lebesgue spaces over some stratified Lie group G $\mathbb{G}$ when the symbol b

The Variation of the Fractional Maximal Function of a Radial Function [PDF]
, 2017 In this paper we study the regularity of the non-centered fractional maximal operator $M_{\beta}$. As the main result, we prove that there exists $C(n,\beta)$ such that if $q=n/(n-\beta)$ and $f$ is a radial function, then $\|DM_{\beta}f\|_{L^{q}(\mathbb{

Quantum entanglement and Bell inequalities in Heisenberg spin chains [PDF]
, 2002 We show that in one-dimensional isotropic Heisenberg model two-qubit thermal entanglement and maximal violation of Bell inequalities are directly related with a thermodynamical state function, i.e., the internal energy.
