Multipoint Normal Differential Operators of Second Order

In this work it is described all normal extensions of a multipoint minimal operator generated by linear multipoint differential-operator expression for second order in the Hilbert space of vector-functions in terms of boundary values at the endpoints of the infnitely many subintervals. Finally, a spectrum structure of such extensions has been investigated.

Compact Inverses of The Multipoint Normal Diferential Operators For First Order

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 vector functions in terms of boundary values at the endpoints of the infinitely many separated subintervals are described. Finally, a compactness properties of the inverses of such extensions has been investigated.
