Stein spaces characterized by their endomorphisms [PDF]

Transactions of the American Mathematical Society, 2010
Finite-dimensional Stein spaces admitting a proper holomorphic embedding of the complex line are characterized, among all complex spaces, by their holomorphic endomorphism semigroup in the sense that any semigroup isomorphism induces either a biholomorphic or an antibiholomorphic map between them.

Stein spaces and Stein algebras [PDF]

Bulletin of the Polish Academy of Sciences. Mathematics
We prove that the category of Stein spaces and holomorphic maps is anti-equivalent to the category of Stein algebras and C-algebra morphisms. This removes a finite-dimensionality hypothesis from a theorem of Forster.

An embedding theorem for Campanato spaces [PDF]

Electronic Journal of Differential Equations, 2002
The purpose of this paper is to give a Sobolev type embedding theorem for the spaces $mathcal{L}_{p,q}^{lambda,s}(mathbb{R}^{n})$. The homogeneous versions of these spaces contain well known spaces such as the Bounded Mean Oscillation spaces (BMO) and ...

On harmonic and 2-stein spaces of Iwasawa type [PDF]

Differential Geometry and its Applications, 2003
A Riemannian manifold \(M\) is called harmonic if its small geodesic spheres have constant mean curvature. Clearly, two-point homogeneous spaces are harmonic. The Lichnerowicz conjecture, stating that the converse is also true, remained an open problem for quite a long time, until \textit{E. Darmek} and \textit{F. Ricci} [J. Geom. Anal.

Trace maps on rigid Stein spaces [PDF]

manuscripta mathematica, 2023
AbstractWe provide a relative version of the trace map from the work of Beyer, which can be associated to any finite étale morphism $$ X \rightarrow Y$$ X → Y of smooth rigid Stein spaces and which then relates the Serre duality on X with ...

Function spaces of BMO and Campanato type [PDF]

Electronic Journal of Differential Equations, 2002
To obtain the Littlewood-Paley characterization for Campanato spaces $mathcal{L}^{2,lambda}$ modulo polynomials (which contain as special case the John and Nirenberg space $BMO$), we define and study a scale of function spaces on $mathbb{R}^{n}$.

Invariant meromorphic functions on Stein spaces [PDF]

, 2012
International audienceIn this paper we develop fundamental tools and methods to study meromorphic functions in an equivariant setup. As our main result we construct quotients of Rosenlicht-type for Stein spaces acted upon holomorphically by complex ...

A note on the Fefferman–Stein inequality on Morrey spaces [PDF]

, 2017
In this paper, we discuss the Fefferman–Stein inequality on Morrey spaces and give a sufficient and necessary condition for which the inequality holds. Further, we give an example of weights such that the Fefferman–Stein inequality on Morrey spaces fails.

Boundedness of Littlewood-Paley Operators Associated with Gauss Measures

Journal of Inequalities and Applications, 2010
Modeled on the Gauss measure, the authors introduce the locally doubling measure metric space (𝒳,d,μ)ρ, which means that the set 𝒳 is endowed with a metric d and a locally doubling regular Borel measure μ ...
