Lorentz type spaces of ultrasmooth vectors of closed operators

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2009
Lorentz type spaces of ultrasmooth vectors of closed operators in Banach spaces are defined. Interpolation properties of such spaces are established and their application to the decision of problem of approaching of elements of Banach space is shown ...
