Abstract

In this paper rstly all maximal accretive extensions of the minimal operator generated by a rst order linear singular quasi-dierential expression in the weighted Hilbert space of vector-functions on right semi-axis are described. Later on, the structure of spectrum set of these extensions has been researched.
