Abstract
In this work, firstly we describe all normal extensions of a minimal operator generated by linear
differential-operator expression of first order in the Hilbert space of vector functions in finite interval.
Later on, we investigate discreteness of spectrum and asymptotical behavior of s-numbers of the
inverses of these normal extensions.
