Exactly today, 7 September, 2017, the founder of fuzzy set theory, Prof. Lotfi Zadeh, passed away at the age of 97. We would like to dedicate this special issue to our scientific father. In his 1965 seminal paper, entitled “Fuzzy sets” Zadeh extended Cantor’s binary set theory to a gradual model by introducing degrees of belonging and relationship. Very soon, this extension has been applied to almost all domains of contemporary mathematics giving birth to new disciplines, such as fuzzy topology, fuzzy arithmetic, fuzzy algebraic structures, fuzzy differential calculus, fuzzy geometry, fuzzy relational calculus, fuzzy databases and fuzzy decision making. In the beginning, mostly direct fuzzyfications of the classical mathematical domains have been launched by simply changing Cantor’s set-theoretic operations by Zadeh’s max-min extensions. The 1980s were characterized by an explosion of the possible fuzzyfications due to the discovery of triangular norms and co-norms. Starting from the nineties more profound analysis has been performed by studying the axiomatization of fuzzy structures and searching for links between the different models to represent imprecise and uncertain information. It is our aim to have in this Special Issue a healthy mix of excellent state-of-the-art papers, as well as brand-new material that can serve as a starting point for newcomers in the field to further develop this wonderful domain of fuzzy mathematics.

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. 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 1600 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.
