This special issue belongs to the section “Mathematics“.
Special Issue Information
Dear Colleagues,
We invite you to submit papers related to various aspects of Functional Equations and Inequalities and their applications including (but not limited to) solution methods of functional equations on various classic as well as abstract structures, characterizations of different mappings and spaces, convex functions (functionals) and their generalizations, stability and functional equations postulated almost everywhere, Hahn-Banach type separation theory, sandwich theorems, theory of means, orthogonal additivity, difference property, alienation of functional equations, iterations (dynamical systems), iterative functional equations, multifunctions and functional inclusions, functional equations in fuzzy logic and fuzzy set theory, invariant means and related topics.
Prof. Dr. Roman Ger
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 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.
