Turkish Journal of Science is a double-blind peer-reviewed international journal that focuses on presenting new ideas of researchers, bringing innovation to science, and publishing research articles in all fields of mathematics. The journal is open access and regularly publishes three times in a year (April- August-December issues). The journal publishes original research articles that written in English, and in order for an article to be published, it must have the potential and motivation to attract the attention of a significant number of researchers and readers. We carry out the article evaluation and publication processes within the framework of the norms we define as much as possible and our priority is always to publish quality and original articles.

The journal encourages the submission of high-quality articles concerning the fundamentals of the following subjects:
approximation theory, fractional calculus, applied functional analysis, linear algebra, discrete mathematics, combinatorics, control theory, financial mathematics, fuzzy sets and logic, game theory, graph theory, information theory, inverse problems, numerical analysis and numerical solutions of ordinary and partial differential equations, operation research.

We would like to thank editorial board members, authors and referees for their unique contributions. Editorial team always carry out extensive studies in order to make the journal a prestigious platform in mathematics.
