Bilinear multipliers and transference.
Let X be a complex Banach space and let Bloch(X) denote the space of X-valued analytic functions on the unit disc such that . A sequence (Tₙ)ₙ of bounded operators between two Banach spaces X and Y is said to be an operator-valued multiplier between Bloch(X) and ℓ₁(Y) if the map defines a bounded linear operator from Bloch(X) into ℓ₁(Y). It is shown that if X is a Hilbert space then (Tₙ)ₙ is a multiplier from Bloch(X) into ℓ₁(Y) if and only if . Several results about Taylor coefficients of vector-valued...
The duality between H1 and BMO, the space of functions of bounded mean oscillation (see [JN]), was first proved by C. Fefferman (see [F], [FS]) and then other proofs of it were obtained. In this paper we shall study such space in little more detail and we shall consider the H1-BMO duality for vector-valued functions in the more general setting of spaces of homogeneous type (see [CW]).
We develop the notion of the -summing power-norm based on a Banach space , where and are symmetric sequence spaces. We study the particular case when and are Orlicz spaces and respectively and analyze under which conditions the -summing power-norm becomes a multinorm. In the case when is also a symmetric sequence space , we compute the precise value of where stands for the canonical basis of , extending known results for the -summing power-norm based on the space which...
We find necessary and sufficient conditions on radial weights w on the unit disc so that the Bergman type projections of Forelli-Rudin are bounded on L¹(w) and in the Herz spaces .
The purpose of this note is to announce some results related to Hardy spaces of vector valued functions and to show that some properties on B have to be required if we want that the classical theorems to remain valid in the B-valued setting.
We consider (p,q)-multi-norms and standard t-multi-norms based on Banach spaces of the form , and resolve some question about the mutual equivalence of two such multi-norms. We introduce a new multi-norm, called the [p,q]-concave multi-norm, and relate it to the standard t-multi-norm.
