The OTHA series of events (Operator Theory and Harmonic Analysis) traditionally includes the main annual conference at SFedU (Rostov-on-Don), workshops, special sections at other conferences, a seminar, and thematic issues in journals (publishing activities). The conferences' topics are significantly broader than their titles, and also include applied sections and sections dedicated to leading scientists.
This year, the first event was a special session at a conference in the UAE (Sharjah), followed by a workshop in Yerevan, the main conference in Rostov-on-Don, an editorial board meeting in Tbilisi, and a final workshop in Sochi (Sirius). At the same time, a research seminar was also held regularly, and two special issues were launched in the Journal of Mathematical Sciences (Springer Nature) and the Lobachevskii Journal of Mathematics (Pleiades Publishing).

Many thanks to all participants, speakers, friends for valuable contributions!
