Special Issue Information

Dear Colleagues,

As is well known in Analysis, Functional Analysis, and their applications, the notions of differentiability, convexity, basic inequalities, and the optimization of scalar- or Banach lattice-valued functions are the foundation for new ideas and findings. This Special Issue focuses on the topics mentioned above as well as their related subjects. More specifically, we aim to study aspects of optimization, polynomial approximations on unbounded subsets, moment problems, variational inequalities, evolutionary problems, dynamical systems, generalized convexity, partial differential equations, and Banach lattices of self-adjoint operators. We will emphasize applications to concrete problems and recognize that some of these research areas are intercorrelated. Therefore, we cordially invite you to publish your findings (articles or review papers) on these or related subjects in this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at 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.
