A Special Issue: Operator Theory and Harmonic Analysis of the Mathematical Methods in the Applied Sciences.

This volume gathers selected, peer-reviewed papers from the "Modern Methods, Problems and Applications of Operator Theory and Harmonic Analysis IX" (OTHA 2019) conference, which was held in Rostov-on-Don, Russia, in April 2019.

This special issue on “Operator Theory and Harmonic Analysis” presents recent advances in the development of methods, approaches, and applications of these important mathematical fields in applied sciences. Presented by leading researchers, the articles notably touch on recent developments in spectral theory, with applications to partial differential equations and to real-world problems, along with deep emphasis on the new trends in operator theory and function spaces theory. We are thankful to the authors for accepting our invitation to contribute.
