Fritz Gesztesy is a Ph.D., renowned Austro–American mathematical physicist and professor of mathematics at Baylor University, USA, known for his important contributions to spectral theory, functional analysis, non-relativistic quantum mechanics (in particular, Schrodinger operators), ordinary and partial differential operators and fully integrable systems (soliton equations). He is the author of more than 300 publications on mathematics and physics. In 1983 he received the Austrian Theodor Kerner Prize in Natural Sciences, and in 1987 the Ludwig Boltzmann Prize from the Austrian Physical Society. In 2002, he was elected to the Royal Norwegian Society of Sciences and Letters. In 2013, he became a member of the American Mathematical Society. In 2022, he received an honorary doctorate from the Graz University of Technology.

On November 14, at the seminar of the Russian Scientific Research Center of the Southern Federal University, Professor Geztezi gave a lecture "Generalized eigenvalue problem for the classical differential Euler equation and the Meyer G-function". He presented a fundamental system of solutions to the generalized eigenvalue problem for the classical higher-order Euler differential equation. In deriving the solution, some fundamentals of generalized hypergeometric functions and Meyer G-functions were considered, as well as some of their special cases.

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 Institute of Mathematics, Mechanics and Computer Science 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.
