Communications in Advanced Mathematical Sciences (CAMS) (Commun. Adv. Math. Sci.) is an international and peer-reviewed journal that publishes high-quality papers on pure and applied mathematics. To be published in this journal, a paper must contain new ideas and be of interest to a wide range of readers. Survey papers are also welcome. The similarity percentage must be less than 30% without bibliography. CAMS provides the readers with free, instant, and permanent access to all content worldwide; and the authors with extensive promotion of published articles, long-time preservation, no space constraints, and immediate publication. No submission or processing fees are required. The journal appears in 4 numbers per year (March, June, September, and December) and has been published since 2018. 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. 11 Number theory 34 Ordinary differential equations 35 Partial differential equations 39 Difference and functional equations 40 Sequences, series, summability 44 Integral transforms, operational calculus 46 Functional analysis 47 Operator theory 52 Convex and discrete geometry 53 Differential geometry 54 General topology Bibliographic Data CAMS, Commun.
