A natural localization of Hardy spaces in several complex variables

Mihai Putinar, Roland Wolff (1997)

Annales Polonici Mathematici

Let H²(bΩ) be the Hardy space of a bounded weakly pseudoconvex domain in n . The natural resolution of this space, provided by the tangential Cauchy-Riemann complex, is used to show that H²(bΩ) has the important localization property known as Bishop’s property (β). The paper is accompanied by some applications, previously known only for Bergman spaces.

A note on a construction of J. F. Feinstein

M. J. Heath (2005)

Studia Mathematica

In [6] J. F. Feinstein constructed a compact plane set X such that R(X), the uniform closure of the algebra of rational functions with poles off X, has no non-zero, bounded point derivations but is not weakly amenable. In the same paper he gave an example of a separable uniform algebra A such that every point in the character space of A is a peak point but A is not weakly amenable. We show that it is possible to modify the construction in order to produce examples which are also regular.

A note on spaces of type H + C

David Stegenga (1975)

Annales de l'institut Fourier

We show that a theorem of Rudin, concerning the sum of closed subspaces in a Banach space, has a converse. By means of an example we show that the result is in the nature of best possible.
