OTHA-2023: Modern methods, problems and applications of operator theory and harmonic analysis

From August 20 to August 25, the international scientific conference "OTHA-2023: Modern methods, problems and applications of operator theory and harmonic analysis" was held at the Southern Federal University. There were participants from various regions of Russia, as well as from Belarus, Armenia, Serbia, UAE, India, Cameroon, Iran, Ecuador, Italy, Georgia, Tajikistan and other countries. During the conference, 4 parallel sessions worked: Functional analysis, operator theory and approximation theory; Differential equations and mathematical physics; Probabilistic-analytical models and methods; Special session dedicated to the memory of Professor S.B. Klimentov.

Conference plenary lecturers: Alexey Karapetyants (Russia/Rostov-on-Don), Adolf Mirotin (Belarus), Krishnan Narayanan (India), Alexander Bufetov (Russia/Moscow), Andrey Muravnik (Russia/Moscow), Francesco Mainardi (Italy), Fedorovsky Konstantin (Russia/Moscow), Apushkinskaya Daria (Russia/Moscow), Rossovsky Leonid (Russia/Moscow), Smorodina Natalia (Russia/St. Petersburg), Soldatov Alexander (Russia/Moscow), Gliklich Yuri (Russia/Voronezh), Yurko Vyacheslav (Russia/Saratov), Arsenovic Milos (Serbia), Jerbashyan Armen (Armenia), Skopina Maria (Russia/St. Petersburg), Ilolov Mamadsho (Tajikistan), Kusraeva Zalina (Russia/Vladikavkaz), Vagharshakyan Armen (Armenia), Khoury Suheil (UAE).

The lectures of the plenary lecturers were recorded and after proper editing will be posted on the Internet on the conference channel (

Selected articles of OTHA-2023 participants will be considered for publication in the scientific journal Journal of Mathematical Sciences (Series A) - editor-in-chief A.N. Karapetyants.
