Special Issue Information

Dear Colleagues,

Approximation theory is concerned with the reconstruction of a function from sampled given data. Such kinds of situations occur when dealing with real world problems, such as reconstruction of geological surfaces, image restoration, demographic data fittings and in all the fields that need to treat big data. Many methods have already been proven as effective numerical tools in this area, such as multivariate splines, RBF and finite element methods (FEM). In this Special Issue, we would like to cover the field of scattered data interpolation/approximation, which includes previously mentioned applications and it is a very recent and fast growing research area.

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 papers will be 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. Axioms is an international peer-reviewed open access quarterly 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 1400 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.
