Abstract

The parametrization of all selfadjoint extensions of the minimaloperator generated by first order linear symmetric singular di¤erential-operatorexpression in the Hilbert space of vector-functions defined at the right semi-axishas been given. To this end we use the Calkin-Gorbachuk method. Finally,the structure of spectrum set of such extensions is researched.
