*On June 13, a lecture by Viktor Kovtunenko, Professor at the Karl and Franz University of Graz, Austria, was held as part of the regular scientific seminar of the SFedU Regional Scientific and Educational Mathematical Center. The seminar was led by Professors Alexey Karapetyants and Vladislav Kravchenko.*

Viktor Anatolyevich Kovtunenko – Ph.D., Professor at the Center for Mathematics and Computer Science of the Karl and Franz University of Graz, Austria, fellow of the Alexander von Humboldt Foundation (Germany), INTAS Foundation (Belgium), FWF Foundation (Austria). In 2017, he was recognized by the IOP (publishing company of the British Institute of Physics) as the outstanding reviewer on inverse problems. In 2018-2019, he was recognized as the scientist with the most frequently downloaded articles by Wiley Publishing House, USA. His research interests include such branches of mathematics as applied mathematics and modeling, mathematical programming, etc.

On June 13, Professor Kovtunenko gave a lecture at the seminar of the RSEMC of the Southern Federal University on the stability of control equations for a quasi-linear viscoelastic model with pressure-dependent modules in which stress and deformation manifest themselves linearly. The quasi-linear viscoelastic model in this problem is given by tensor hereditary integrals with kernels of aging or convolution memory.

The seminar "Seminar on Analysis, Differential Equations and Mathematical Physics" was attended by more than thirty mathematicians - specialists from leading scientific and educational centers of the world in Russia and other countries, including graduate students and students of the Faculty of Mechanics and Mathematics of the Southern Federal University and young scientists.

Online scientific seminar of the Regional Scientific and Educational Mathematical Center (https://rmc.sfedu.ru /) it is held regularly every two weeks, announcements of new seminars and videos of previous seminars are available on the website http://msrn.sfedu.ru/sl . The seminar is attended by leading researchers from around the world whose research interests are related to analysis, differential equations and mathematical physics. The scientific seminar of the mathematical center is open, and everyone can take part in it.

The language of the seminar is English.
