OTHA SPECIAL SESSION

within the 13th ISAAC Congress

Ghent, Belgium / Zoom

А special session OTHA (Operator Theory and Harmonic Analysis) within the 13th ISAAC Congress will be held on 2-6 August 2021 Ghent, Belgium, see List of sessions. The conference will be organized as an online event via Zoom.
The session Operator Theory and Harmonic Analysis invites papers dealing with theoretical and applied harmonic analysis and operator theory: real and complex variable methods, function spaces, including nonstandard growth functions, applications to PDE’s, mathematical modelling based on the pure/applied harmonic analysis and exploration of new themes and trends, including related multidisciplinary studies. These include methods of harmonic analysis and operator theory which arise in theory and practice of partial and ordinary differential equations, spectral theory, direct and inverse problems, special functions, etc.

Session is supported by Regional Mathematical Center SFedU, project the Ministry of Science and Higher Education RF, agreement № 075-02-2021-1386.
We expect to have some selected papers published in a Proceedings or in a special issue of a peer-reviewed journal, this will be specified later on.
We welcome everyone interested in participating in our session to contact directly to the section coordinators Alexey Karapetyants (karapetyants@gmail.com) and Vladislav Kravchenko (vkravchenko@math.cinvestav.edu.mx).
