Singular degenerate normal operators for first-order

Fatih Yilmaz; Meltem Sertbas;


In this paper, all normal extensions of the minimal operator associated with the singular degenerate linear differential expressions for fi rst order in the Hilbert space of vector-functions are investigated in terms of boundary values. As well, it analyzes the spectrum parts of any normal extension.
