Definition and Properties of the Libera Operator on Mixed Norm Spaces by Miroslav Pavlovic

“…We consider the action of the operator ℒg(z)=(1-z)-1∫z1‍f(ζ)dζ on a class of “mixed norm” spaces of analytic functions on the unit disk, X=Hα,νp,q, defined by the requirement g∈X⇔r↦(1-r)αMp(r,g(ν))∈Lq([0,1],dr/(1-r)), where 1≤p≤∞, 0<q≤∞, α>0, and ν is a nonnegative integer. This class contains Besov spaces, weighted Bergman spaces, Dirichlet type spaces, Hardy-Sobolev spaces, and so forth. …”
