On 21^th December  2022 at 10:00 at the seminar of the Institute of Mathematics and Mechanics  head of the laboratory “Mathematical Problems of Signal Processing” Ph.D., Assoc. prof. Sabina Rahib kizi Sadigova will speak with the presentation entitled “On the abstract analogue of the 1/4-Kadets theorem”.

In the report some information about the study of the basis properties of perturbed systems of exponents in Lebesgue spaces will be given. An abstract analogue of the Riemann boundary value problem is considered and a sufficient condition for its correct solvability  is found. The application of this approach to obtaining an abstract analogue of the famous “1.4-Kadets” theorem is considered.
