Invariant subspaces on open Riemann surfaces

Morisuke Hasumi (1974)

Annales de l'institut Fourier

Let R be a hyperbolic Riemann surface, d χ a harmonic measure supported on the Martin boundary of R , and H ( d χ ) the subalgebra of L ( d χ ) consisting of the boundary values of bounded analytic functions on R . This paper gives a complete classification of the closed H ( d χ ) -submodules of L p ( d χ ) , 1 p (weakly * closed, if p = , when R is regular and admits a sufficiently large family of bounded multiplicative analytic functions satisfying an approximation condition. It also gives, as a corollary, a corresponding result for the Hardy...

Invariant subspaces on open Riemann surfaces. II

Morisuke Hasumi (1976)

Annales de l'institut Fourier

We considerably improve our earlier results [Ann. Inst. Fourier, 24-4 (1974] concerning Cauchy-Read’s theorems, convergence of Green lines, and the structure of invariant subspaces for a class of hyperbolic Riemann surfaces.

Iterates and the boundary behavior of the Berezin transform

Jonathan Arazy, Miroslav Engliš (2001)

Annales de l’institut Fourier

Let μ be a measure on a domain Ω in n such that the Bergman space of holomorphic functions in L 2 ( Ω , μ ) possesses a reproducing kernel K ( x , y ) and K ( x , x ) > 0 x Ω . The Berezin transform associated to μ is the integral...

Le dual de l'espace des fonctions holomorphes intégrables dans des domaines de Siegel

David Bekolle (1984)

Annales de l'institut Fourier

Nous répondons à une conjecture de R. Coifman et R. Rochberg : dans le complexifié du cône sphérique de R n + 1 , le dual de la classe de Bergman A 1 s’obtient comme projection de Bergman de L et coïncide avec la classe de Bloch des fonctions holomorphes. Nous examinons également le cas d’un produit de domaines.

Linear topological properties of the Lumer-Smirnov class of the polydisc

Marek Nawrocki (1992)

Studia Mathematica

Linear topological properties of the Lumer-Smirnov class L N ( n ) of the unit polydisc n are studied. The topological dual and the Fréchet envelope are described. It is proved that L N ( n ) has a weak basis but it is nonseparable in its original topology. Moreover, it is shown that the Orlicz-Pettis theorem fails for L N ( n ) .
