Fundamental Journal of Mathematics and Applications (FUJMA), (Fundam. J. Math. Appl.) started indexing in TR Index from 2021 and in DOAJ from 2023. On the other hand FUJMA will be published four times a year , at intervals of three months (March, June, September and December) , and only in online version. FUJMA , 2645-8845 (online), is a double blind peer reviewed Open Access journal that publishes original research articles, review articles and survey articles related to Mathematics. Open access means that articles published in FUJMA are available online to the reader “without financial, legal, or technical barriers”. We publish online versions. Accepted paper will be published online immediately after it gets ready to publish. Similarity percentage must be less than 30% without bibliography. No submission or processing fees are required. The journal appears in 4 numbers per year and has been published since 2018. Survey papers are also welcome. FUJMA policy normally permits a maximum of 1 (one) paper per calendar year, per author and co-author. According to the Mathematics Subject Classification – MSC2020 classification, our subject areas are as follows. However, if a subject other than the Mathematics Subject Classification subject areas comes up, it can be taken into the process with the decision of the Editorial Board. 15 Linear and multilinear algebra; matrix theory 26 Real functions 30 Functions of a complex variable 33 Special functions 34 Ordinary differential equations 35 Partial differential equations 39 Difference and functional equations 40 Sequences, series, summability 41 Approximations and expansions 44 Integral transforms, operational calculus 45 Integral equations 46 Functional analysis 47 Operator theory 65 Numerical analysis The average time during which the preliminary assessment of manuscripts is conducted: 3 days The average time during which the reviews of manuscripts are conducted: 60 days The average time in which the article is published: 90 days
