workshop poster otha spring 24.jpg
International scientific workshop OTHA Spring 2024 will be held on 21-25 April 2024 in Institute of Mathematics of NAS RA (Yerevan).

21 April - arrival
22-23 April - working days
24 April - excursion
25 April - departure

The program of the workshop will include a number of invited lectures.


OTHA workshops are part of the OTHA conference/workshops/seminars/editorial activities https://otha.sfedu.ru/ , http://msrn.sfedu.ru/

The special (thematical) issue in the Lobachevskii Journal of Mathematics.

Following the workshop, a special thematic issue is planned in the Lobachevskii Journal of Mathematics (Springer Nature) https://www.springer.com/journal/12202 . Interested researchers and participants of OTHA Spring 2024 are welcome to submit their manuscripts. This is an extended edition in the sense that all participants of the OTHA events who did not necessarily attend the conference in person are invited as well. Deadline for submission: June 30th., 2024. However, the number of articles is limited, therefore acceptance of articles will be closed once the required number (10-12 articles) will be reached.

The special (thematical) issue in the Journal of Mathematical Sciences (OTHA-2024).

Of course, there is always the opportunity to submit a manuscript to a special issue of OTHA-2024 in the Journal of Mathematical Sciences (Springer Nature) https://www.springer.com/journal/10958 , which will collect selected articles from OTHA events in 2024. There is no deadline for this issue, and articles will be published as they are accepted.

Journal of Mathematical Sciences (Series A) is a partner of OTHA conference series.

Journal of Mathematical Sciences (Series A) publishes articles covering a wide range of topics, including mathematical analysis, probability, statistics, mathematical physics, PDE's, etc. The submitted articles must be written in English and should be in the broad focus of the journal (see Aims and Scope). The regular review policy will be applied to each paper. Submissions must meet high scientific publication standards with clear evidence of the novelty and scientific importance of the results.

Conference is supported by the Regional Mathematical Center of SFedU, a project of the Ministry of Science and Higher Education RF, agreement № 075-02-2024-1427.
