Algebras of symmetric holomorphic functions of several complex variables

open access: closedRevista Matemática Complutense, 2018
Let \(g:\Omega\longrightarrow\Omega'\) be a proper holomorphic mapping, where \(\Omega\subset\mathbb C^n\), \(\Omega'\subset\mathbb C^k\), \(k\geq n\). Given an algebra \(\mathcal B(U)\) of functions defined on a set \(U\subset\Omega\) (e.g., \(\mathcal P(K)\), \(\mathcal O(U)\), \(\mathcal A(U)\), \(\mathcal H^\infty(U)\)) the authors study properties

Distortion Properties of Holomorphic Functions of Several Complex Variables

open access: closedMathematische Nachrichten, 1980
Let Q(D) be a class of functions q, q(0) = 0, |q(z)| < 1 holomorphic in the Reinhardt domain D ⊂ Cn, a and b — arbitrary fixed numbers satisfying the condition — 1 ≤ b < a ≤ 1. 𝔭(a, b; D) — the class of functions p such that p ϵ 𝔭(a, b; D) iff for some q ϵ Q(D) and every z ϵ D. S*(a, b; D) — the class of functions f such that f ϵ S*(a, g;

Embedding theorems for holomorphic functions of several complex variables

open access: closedJournal of Applied Analysis, 2013
Summary: Many authors studied families \(\mathcal X_{\mathcal G}\) of complex valued functions, which are holomorphic in bounded complete \(n\)-circular domains \(\mathcal G \subset \mathbb C^n\) and fulfil some geometric conditions. The above functions were applied later to study families of locally biholomorphic mappings in \(\mathbb C^{n}\). In this

Admissible limits of normal holomorphic functions of several complex variables

open access: closedMathematical Notes of the Academy of Sciences of the USSR, 1990
Let \(D\subset {\mathbb{C}}^ n\) (n\(\geq 2)\) be a domain with \(C^ 2\)- boundary. We say that a function \(f\in {\mathcal O}(D)\) is normal if there exists a constant M such that \({\mathcal L}_{\log (1+| f|^ 2)}(z;v)\leq M\kappa_ D(z;v)\), \(z\in D\), \(v\in {\mathbb{C}}^ n\), where \({\mathcal L}\) denotes the Levi form and \(\kappa_ D\) is the ...

The convergence of Padé-type approximants to holomorphic functions of several complex variables

open access: closedApplied Numerical Mathematics, 1990
The author proves two generalizations of \textit{M. Eiermann's} [J. Comput. Appl. Math. 10, 219-227 (1984; Zbl 0538.65011)] sufficient condition for linear summability of power series, one where the summation method is applied to partial sums of the multidimensional power series and one where different summation matrices are used in different variables.

HOLOMORPHIC FUNCTIONS OF SEVERAL COMPLEX VARIABLES WITH NONNEGATIVE REAL PART. TRACES OF HOLOMORPHIC AND PLURIHARMONIC FUNCTIONS ON THE ŠILOV BOUNDARY

open access: closedMathematics of the USSR-Sbornik, 1976
For a certain class of domains, conditions are given which a continuous function on the Silov boundary of a domain must satisfy in order that there exist a holomorphic (pluriharmonic) function in , continuous on and such that . Bibliography: 24 titles.

A boundary uniqueness theorem for holomorphic functions of several complex variables

open access: closedMathematical Notes of the Academy of Sciences of the USSR, 1974
If D ⊂ Cn is a region with a smooth boundary and M ⊂ ∂D is a smooth manifold such that for some point p ∈ M the complex linear hull of the tangent plane Tp(M) coincides with Cn, then for each functionf e A(D) the conditionf¦M=0 implies thatf=0 in D.

Groups of linear isometries of spaces M q of holomorphic functions of several complex variables

open access: closedMathematical Notes, 2008
Let \(G\) be the unit ball or the unit polydisk in \(\mathbb C^n\) and \(\Gamma\) be the Bergman-Shilov boundary of \(G\). Let \(M^q\) be the class of all holomorphic functions \(f\) in \(G\) such that \[ \int \limits_{\Gamma} (\ln^+ \{\sup \limits_{0 \leq r < 1} |f (r \zeta)|)^q \sigma (d \zeta) < + \infty, \] where \(\sigma\) is an invariant ...

I Elementary local properties of holomorphic functions of several complex variables

open access: closed, 2010
In this chapter we study the local properties of holomorphic functions of several complex variables which can be deduced directly from the classical theory of holomorphic functions in one complex variable. The basis for our work is a Cauchy formula for polydiscs which generalises the classical Cauchy formula. Most of the theorems proved in this chapter

Extensions of p-Yosida functions to holomorphic mappings of several complex variables

open access: closedComplex Variables and Elliptic Equations, 2019
Let M be a complete complex Hermitian manifold with metric EM. A holomorphic mapping f:Cm→M is called p-Yosida mapping if ∥z∥2−pEM(f(z),df(z)(ξ)) is bounded above for z,ξ∈Cm with ∥ξ∥=1, where df(z)...
