Symmetry in Approximation Theory and Functional Analysis

Dear Colleagues,

We welcome interdisciplinary interactions between approximation theory and functional analysis. This Special Issue covers all possible connections between these two areas with special attention to properties concerning symmetry, such as, for instance, the relationship of the convergence of some algorithms using symmetric bases in Banach (or quasi-Banach) spaces. In particular, results are welcome on, but not limited to:

• Algorithms in optimization theory;
• Symmetric approximations of frames;
• Related properties of symmetry to study the convergence of algorithms;
• Studies of the best approximation using some symmetric properties;
• Abstract approximations;
• Symmetric bases;
• Machine learning and approximations;
• Wavelet theory and its applications;
• Orthogonal polynomials;
• Fourier expansions.

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 250 words) can be sent to the Editorial Office for assessment.

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. Symmetry is an international peer-reviewed open access monthly 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 2400 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.
