**RATIO MATHEMATICA - JOURNAL OF MATHEMATICS, STATISTICS, AND APPLICATIONS**

Ratio Mathematica is an International, double peer-reviewed, open access journal, published every six months (June-December). This periodical has a long tradition, indeed its first issue was published in 1990. It aims to publish original research articles in the fields of Mathematics and Statistics. However, contributions with applications of Mathematics and Statistics to Social Science, Business Administration, Engineering, Programming, Economics, Management, Fuzzy Logic, and Probability, are welcome. Only English-language publications are accepted.

The main topics of interest for Ratio Mathematica are:

**Foundations of Mathematics:** Epistemology of Mathematics, Critique of the Foundations of Mathematics, Elementary Mathematics from a higher point of view, Elementary Theory of Numbers, Foundations of Mathematics of Uncertain; Criticism of the Foundations of Computer Science.

**Applications of Mathematics:** Applications to Engineering and Economics, Applications for Management and Business Administration, Decision making in conditions of uncertainty, Theory of Games, Fuzzy Logic and Applications, Probability, Statistics and Applications.

**New theories and applications:** Algebraic hyperstructures and Applications, Discrete Mathematics and Applications, Fuzzy structures.

**New theories and practices for dissemination and communication of mathematics:** Communication of History and Fundations, Communication of Discrete Mathematics, Communication of Probability and Statistics, Communication with Media.

**Indexing**: Ratio Mathematica is abstracted and indexed in:

PKP (Public Knowledge Project)

The **indexing procedures** were initiated in late 2016, then short the journal will be indexed in several other international databases.

The printed copies of the journal are stored at the **National Library of Florence** and **Provincial Library of Pescara, Italy**.
