Operator calculus on ultrasmooth vectors
A general method of constructing functions of unbounded operators acting in Banach spaces is set forth. It is based on equipping the initial space with invariant subspaces of ultradifferential vectors of a specified operator and describing the spectral properties of the initial space in the topologi...
