Название: On the existence of solution of boundary value problems
Автор: Humbataliyev R. Z.
Аннотация:
The suggested book is devoted to similar questions of solvability of operatordifferential equations of higher order and boundary value problems for them, to investigation of spectral properties of appropriate operator pencils. A theorem of Phragmen-Lindeloff type in some vector is proved. The principal part of the investigated operator-differential equations have multiple characteristics.
