Characteristic Numbers of Upper Triangular One-Band Block Operator Matrices
In this work the boundedness and compactness properties of upper triangular one-band block operator matrices in the infinite direct sum of Hilbert spaces have been studied. We also obtain the necessary and sufficient ... -
Discreteness of Spectrum of Normal Differential Operators for First Order
In this work under the condition A?1 ? C?(H), we investigate the discreteness of spectrum of normal extensions in detail. Later on, the asymptotical behavior of eigenvalues of any normal extension has been examined. -
Dissipative canonical type differential operators for first order
In this paper, using the Calkin-Gorbachuk method, the general form of all maximally dissipative extensions of the minimal operator generated by the first order linear symmetric canonical type quasi-differential expression ... -
First order self-adjoint multipoint quasi-differential operators

Maximal sectorial differential operators for first order
In this study, the maximal sectorial linear relations are described. Then, the discreteness of the spectrum of the linear maximal sectorial operators and asymptotical behavior of the eigenvalues of such operators in terms ... -
