Karapetyants (Professor of the Institute of Mathematics, Mechanics and Computer Sciences and Director of the SFedU Scientific Research Center) and R.G.Aramyan (Director of the Institute of Mathematics).

The conference was attended by scientists in the field of operator analysis and theory from about 10 countries, including scientists from Russia, Armenia, Portugal, Mexico, Austria, Finland, Italy, USA, Georgia, Germany.

This year, the traditional conference program was supplemented with reports on artificial intelligence. Leading Russian and foreign scientists have performed in this area.

As a result of the workshop, special issues will be prepared in the journals Journal of Mathematical Sciences (Springer Nature) and Lobachevsky Journal of Mathematics (Kazan).

A round table discussion "Development of Series A in the Journal of Mathematical Sciences and International Teams of Guest Editors" was held as part of the conference. The event was organized with the support of the laboratory "Analytical Methods in Geodesy, Cryptography and Machine Learning" (https://sites.google.com/view/labmagic ) and is aimed at discussing strategies for the development of scientific journals, increasing their international visibility and increasing the participation of research communities in editorial activities.

The OTHA Spring and OTHA Fall workshops are held in the spring and winter of each year and are part of the OTHA conference series: https://otha.sfedu.ru / , http://msrn.sfedu.ru /.
