The next seminar of the Faculty of Mechanics and Mathematics was held


In his talk, the speaker considered the Bessel and Hilbert systems in Banach spaces. The talker spoke out about the Banach spaces of scalar sequences, which forms the basis of the system of canonical unit vector. The presenter introduced the generalization of the Bessel and Hilbert systems. Some properties and relations between these systems were discussed.

Finally, speaker answered the questions of the seminar participants.
