Special Issue Information

Dear Colleagues,

Harmonic analysis is one of the core areas of modern analytical mathematics. Over the centuries, it has formed a huge subject system and has important and profound applications in the fields of mathematics, information processing, probability, and quantum mechanics.

This Special Issue, entitled “Recent Advances in Harmonic Analysis and Applications”, is devoted to collecting research papers on the recent progress in harmonic analysis, as well as some applications in various fields of mathematics, such as partial differential equations, probability, and geometry. We would like to invite original research articles that provide new results in this subject. All topics in harmonic analysis and related applications are welcome, in particular, the theory of linear and multilinear Calder\'{o}n-Zygmund operators, real analysis and abstract analysis, etc. Potential topics can be related to, but are not limited to, the keywords listed below. 

Prof. Dr. Qingying Xue
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This paper is devoted to exploring the mapping properties for the commutator μΩ,b generated by Marcinkiewicz integral μΩ with a locally integrable function b in the generalized Campanato spaces on the generalized Morrey spaces. Under the assumption that the integral kernel Ω satisfies certain log-type regularity, it is shown that μΩ,b is bounded on the generalized Morrey spaces with variable growth condition, provided that b is a function in generalized Campanato spaces, which contain the BMO(Rn) and the Lipschitz spaces Lipα(Rn) (0<α1) as special examples. Some previous results are essentially improved and generalized. Full article

In this article, the authors study the boundedness of the vector-valued inequality for the intrinsic square function and the boundedness of the scalar-valued intrinsic square function on variable exponents Herz spaces K˙ρ(·)α,q(·)(Rn). In addition, the boundedness of commutators generated by the scalar-valued intrinsic square function and BMO class is also studied on K˙ρ(·)α,q(·)(Rn). Full article

Let M be the Doob maximal operator on a filtered measure space and let v be an Ap weight with 1<p<+. We try proving that MfLp(v)p[v]Ap1p1fLp(v), where 1/p+1/p=1. Although we do not find an approach which gives the constant p, we obtain that MfLp(v)p1p1p[v]Ap1p1fLp(v), with limp+p1p1=1. Full article

In this survey, we review the historical development for the Carleson problem about the a.e. pointwise convergence in five aspects: the a.e. convergence for generalized Schrödinger operators along vertical lines; a.e. convergence for Schrödinger operators along arbitrary single curves; a.e. convergence for Schrödinger operators along a family of restricted curves; upper bounds of p for the Lp-Schrödinger maximal estimates; and a.e. convergence rate for generalized Schrödinger operators along curves. Finally, we list some open problems which need to be addressed. Full article
