We prove that the classical results by Rodin and Semenov and by Lindenstrauss and Tzafriri on the subspace generated by the Rademacher system in rearrangement invariant spaces also hold for lacunary Walsh series. 相似文献

We improve a recent result of Yang and Xu (Arch. Math. 96 (2011), 151–160) by proving that if ψ is a normal function on [1, ∞) and \({f(z)=\sum_{n=0}^\infty a_n z^{k_n}}\) (|z| < 1) is an analytic function with Hadamard gaps, thenwhere C is a constant independent of ζ and {a n }.

The well-known Paley inequalities for lacunary series are applied in investigation of weighted spaces H(p, α) and H(p, log(α)) of functions holomorphic in the unit disc of the complex plane. These are spaces which are similar to the Bloch and Hardy spaces and naturally arise as the images of some fractional operators. 相似文献

In the spaces of analytic functions f in the unit disk with mixed norm and measure satisfying the Δ2-condition, sharp necessary conditions on subsequences of zeros $\{ z_{n_k } (f)\} $ of the function f are obtained in terms of subsequences of numbers {n k }. These conditions can be used to define, in the spaces with mixed norm, subsets of functions with certain extremal properties; these subsets provide answers to a number of questions about the zero sets of the spaces under consideration and, in particular, about weighted Bergman spaces. 相似文献

We show that the Calderón--Lozanovskii; construction φ(.) commutes with arbitrary mixed norm spaces, that is, φ(E0[F0], E1[F1]) = φ(E0, E1) [φ(F0, F1)] if and only if φ is equivalent to a power function. This result we obtain by giving characterizations of the corresponding
embeddings of φ(E0[F0], E1[F1]) into φ0 (E0, E1)[φ1 (F0, F1)] and vice versa in terms of the functions φ, φ0, φ1. As a particular case, we get embeddings of an Orlicz space with mixed norms into an Orlicz space on a product of measure
spaces. Applications to classical operators between mixed norm Orlicz spaces are also discussed.

The main goal of this paper is to prove the following statement. Let
be a function holomorphic and of bounded characteristic in the unit disk
, where E is a Λ(1)-subset of ℤ+. Assume that f has a pseudocontinuation of bounded characteristic to the annulus {zɛℂ:1<|z|<R}. Then f admits analytic continuation
to the disk R
. In particular, f is a polynomial if R=+∞. Bibliography: 16 titles.

We study the behavior of counting functions of zeros of analytic in a disk functions in spaces with mixed norm, in particular, the Bergman-Dzhrbashyan spaces with standard weights. We obtain corollaries that strengthen the known results on zero sets of spaces with mixed norm. 相似文献

Let Ω be a bounded convex domain with C2 boundary in C2 and for given 0 < p, q ≤∞ and normal weight function (r) let Hp,q, be the mixed norm space on Ω. In this paper we prove that the Gleason's problem (Ω, a, Hp,q,) is solvable for any fixed point a ∈ Ω. While solving the Gleason's problem we obtain the boundedness of certain integral operator on Hp,q,. 相似文献

A new lacunary set for compact abelian groups is introduced; this is called a set. This set is defined in terms of the Lorentz spaces and is shown to be a generalization of sets and Sidon sets. A number of functional-analytic statements about sets are established by making use of the structural similarities between spaces and Lorentz spaces. These statements are analogous to several well-known properties of a set which are equivalent to the definition of a set. Some general set-theoretic and arithmetic properties of sets are also developed; these properties extend known results on the structure of sets. Open problems and directions for further research are outlined.
