Abstract:
Based on methods of operator theory, we describe all boundedly solvable
extensions of the minimal operator generated by a linear multipoint
functional differential-operator expression of first order, in a direct
sum of Hilbert space of vector-functions. We also study the
structure of spectrum of these extensions.
