February 26, 2018. A joint meeting with the seminar of the Laboratory of Mathematical Problems of Physics. Dedicated to the memory of L.D.Faddeev.
M. A. Semenov-Tian-Shansky. Scattering on the Poincaré upper half-plane, Riemann hypothesis, intertwining operators and Huygens principle.

The famous paper of Faddeev and Pavlov published 45 years ago established a link between scattering theory for the wave equation on non-compact Riemann surfaces and the Riemann hypothesis. I shall describe this approach as well as the links between the Harmonic analysis on semisimple Lie groups and symmetric spaces and scattering theory.

List of talks at previous sessions of the seminar.
