چکیده
Let H be the Drury-Arveson or Dirichlet space of unit ball Cd. The weak product ? is collection all functions h that can written as =??n=1 fngn, where ??n=1 ||fn|| ||gn|| < ?. We show contained in Smirnov class H; is, every function a quotient two multipliers H, denominator chosen to cyclic . As consequence, we map N ? closH ?H establishes one-to-one and onto correspondence between multiplier invariant subspaces results hold for many weighted Besov spaces Cd provided reproducing kernel has complete Pick property. One our main technical lemmas states that, satisfy what call inclusion condition, any bounded column multiplication operator ??n=1 induces row For Hd2 this leads an alternate proof characterization interpolating sequences terms separation Carleson measure conditions.

Generalized multivalued $F$-weak contractions on complete metric spaces
In this paper, we introduce the notion of generalized multivalued $F$- weak contraction and we prove some fixed point theorems related to introduced contraction for multivalued mapping in complete metric spaces. Our results extend and improve the results announced by many others with less hypothesis. Also, we give some illustrative examples.
متن کاملSpaces of Dirichlet series with the complete Pick property
We consider reproducing kernel Hilbert spaces of Dirichlet series with kernels of the form k(s, u) = ∑ ann −s−ū, and characterize when such a space is a complete Pick space. We then discuss what it means for two reproducing kernel Hilbert spaces to be “the same”, and introduce a notion of weak isomorphism. Many of the spaces we consider turn out to be weakly isomorphic as reproducing kernel Hil...

متن کاملWeak complete parts in semihypergroups
In this article we generalize the notion of complete parts, by introducing a weaker condition in definition. Using this generalization we define and analyse a new class of semihypergroups, which are called weak complete semihypergroups. Complete parts were introduced about 40 years ago by M. Koskas and they represent a basic notion of hyperstucture theory, utilized in constructing an important ...
متن کاملComplete Nevanlinna-Pick Kernels
We give a new treatment of Quiggin’s and McCullough’s characterization of complete Nevanlinna-Pick kernels. We show that a kernel has the matrix-valued NevanlinnaPick property if and only if it has the vector-valued Nevanlinna-Pick property. We give a representation of all complete Nevanlinna-Pick kernels, and show that they are all restrictions of a universal complete Nevanlinna-Pick kernel.
