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 ... -
Representation of all maximally accretive differential operators for first order
In the present paper, we construct the minimal and maximal operators generated by special type linear differential-operator expression for first order in the weighted Hilbert space of vector-functions defined on right ...
