The next scientific seminar of the Mechanics and Mathematics faculty

The talk is devoted to studying the Bessel and Hilbert systems in Banach spaces. The speaker will consider the Banach spaces of scalar sequences, which forms the basis of the system of canonical unit vectors. The presenter will introduce the generalization of the Bessel and Hilbert systems. Some properties and relations between these systems will be discussed. By the speaker will construct examples of the non-minimal Bessel systems.

We invite all of you to attend our seminar.
