## ATTENTION

05/01/2023On January 10, 2023 at 10:15 a.m., a scientific seminar will be held at the Faculty of Mechanics and Mathematics in room 506. Associate Professor of the Department of Higher Mathematics, Ph.D. Sevda Elkhan kyzy Isaeva with a report on the topic "Investigation of solutions of a mixed problem with a conjugate acoustic condition for hyperbolic equations with unfocused nonlinear sources".

The report will consider a mixed problem with a conjugate acoustic condition for hyperbolic equations with unfocused nonlinear sources. A theorem on the existence and uniqueness of a solution to this problem will be proved. It will be shown below that the subgroup generated by the problem under consideration has a finite absorbing set and the asymptotic compactness of this subgroup. As a result, a result will be obtained on the existence of a minimal global attractor of the problem under consideration.
