Abstract

In this work, in terms of boundary values all normal extensions of the minimal operator generated by a linear singular differential- operator expression for first order with operator coefficients in Hilbert space of vector-functions in a right half-infinite interval are described. Later on, a point spectrum of such extensions has been investigated.
