Scope

Aims, scope and focus

Proceedings of the Japan Academy Series A Mathematical Sciences is published by Japan Academy and is in Zone 4 of Mathematics in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Algebraic Geometry and Number Theory, Advanced Algebra and Geometry and Advanced Topics in Algebra, together about 21.7% of its articles. Its main subfields are Geometry and Topology and Mathematical Physics. (generated from OpenAlex topic counts and CAS ranking data)

The aim of the Proceedings of the Japan Academy, Series A, is the rapid publication of original papers in mathematical sciences. The paper should be written in English or French (preferably in English), and at most 6 pages long when published. A paper that is a résumé or an announcement (i.e. one whose details are to be published elsewhere) can also be submitted. The paper is published promptly if once communicated by a Member of the Academy at its General Meeting, which is held monthly except in July and in August.
