Nikolaos Pallikarakis– PhD, postdoctoral Fellow at the Athens Polytechnic University, Greece, author of about 20 scientific publications. He is engaged in research in the field of forward and reverse spectral problems, backscattering, and the application of machine/deep learning to inverse problems.

On March 6, Nikolaos Pallikarakis gave a lecture at the seminar of the Russian Scientific Research Center of the Southern Federal University on the history, modern research and further prospects for direct and inverse spherically symmetric eigenvalue problems of the scattering operator. The study of the eigenvalues of this type of operators plays an important role in the theory of backscattering. In this report, the problem of eigenvalues of the scattering operator was considered in the context of a spherically symmetric refractive index.

The seminar "Seminar on Analysis, Differential Equations and Mathematical Physics" was attended by about forty mathematicians - specialists from the world's leading scientific and educational centers in Russia and other countries, including graduate students and students of the SFedU Faculty of Mechanics and Mathematics 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 features 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, everyone can take part in it.
