Spectrum of the Direct Sum of Operators
E. Otkun Cevik, Z. I. Ismailov
In this work, a connection between some spectral properties of direct sum of operators in the direct sum of Hilbert spaces and its coordinate operators has been investigated.
On the Maximal Sectorial Operators
Z. I. Ismailov, R. Ozturk
In this work, firstly the maximal sectorial linear relations are described. Later on, the discreteness of the spectrum of the linear maximal sectorial operators and asymptotical be…
Compact Inverses of The Multipoint Normal Diferential Operators For First Order
E. Unluyol, E. Otkun Cevik, Z. I. Ismailov
In this work, firstly all normal extensions of a multipoint minimal operator generated by linear multipoint diferential-operator expression for first order in the Hilbert space of…

Selfadjoint Extensions of a Singular Multipoint Differential Operator for First Order
Zameddin I. Ismailov, Rukiye Ozturk Mert
In this work, firstly in the direct sum of Hilbert spaces of vector-functions L^2 (H,(-{\infty},a_1)){\Box}L^2 (H,(a_2,b_2)){\Box}L^2 (H,(a_3,+{\infty})),- {\infty}<a_1<a_2<b_2<a_3…
