JMS A.PNGJournal of Mathematical Sciences (JMS, Series A) is an official partner of the OTHA conferences/workshops. JMS (Series A) now publishes direct submissions. We are happy to inform you that selected contributions from the OTHA-2023 participants will be considered for publication in the Journal of Mathematical Sciences (Series A). If you intend to contribute a manuscript, you are most welcome to send your inquiries to Mrs. Elena Bagler, Editorial Assistant,

We may have a limited number of grants for early-career mathematicians to attend OTHA-2023 conference. An inquiry that includes a Cover Letter along with CV of the applicant should be submitted to The applications are considered on the first come first served basis.
