Ismailov %J Mathematics %D 2011 %I arXiv %X 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. %U http://arxiv.org/abs/1105.2619v1
