A schlichtness theorem for envelopes of holomorphy [PDF]

open access: yesMathematische Zeitschrift, 2006
Let Omega be a domain in C^2. We prove the following theorem. If the envelope of holomorphy of Omega is schlicht over Omega, then the envelope is in fact schlicht. We provide examples showing that the theorem is not true in C^n, n>2. Additionally, we show that the theorem cannot be generalized to provide information about domains in C^2 whose ...

Envelopes of holomorphy and extension of functions of bounded type

open access: yesAdvances in Mathematics, 2012
We study the extension of holomorphic functions of bounded type defined on an open subset of a Banach space, to larger domains. For this, we first characterize the envelope of holomorphy of a Riemann domain over a Banach space, with respect to the algebra of bounded type holomorphic functions, in terms of the spectrum of the algebra.

Analytic Structure of Amplitudes in Gauge Theories with Confinement [PDF]

open access: yes, 1994
For gauge theories with confinement, the analytic structure of amplitudes is explored. It is shown that the analytic properties of physical amplitudes are the same as those obtained on the basis of an effective theory involving only the composite ...

Group actions and envelopes of holomorphy

open access: yesMathematische Annalen, 1994
Suppose \(K\) is a compact Lie group and \(X\) is a Stein manifold on which \(K\) and its complexification \(K^{\mathbb{C}_ C}\) acts as groups of biholomorphic transformations. Assume \(\Omega\) is a \(K\)-invariant domain in \(X\). The present paper is concerned with the problem of determining the envelope of holomorphy \(E(\Omega)\) of \(\Omega ...

Envelopes of holomorphy and polynomial hulls

open access: yesMathematische Annalen, 1988
This paper continues the study of polynomial hulls by the authors. Let Y be a compact subset of \({\mathbb{C}}^ 2\) contained in \(\partial \Delta \times \Delta\), where \(\Delta\) is the open unit disk in the plane such that for \(\lambda\in \partial \Delta\) the complement of \(Y_{\lambda}:=\{w:\) (\(\lambda\),w)\(\in Y\}\) is connected.

Bochner-Hartogs type extension theorem for roots and logarithms of holomorphic line bundles [PDF]

open access: yes, 2011
We prove an extension theorem for roots and logarithms of holomorphic line bundles across strictly pseudoconcave boundaries: they extend in all cases except one, when dimension and Morse index of a critical point is two.

Levi problem and semistable quotients

open access: yes, 2012
A complex space $X$ is in class ${\mathcal Q}_G$ if it is a semistable quotient of the complement to an analytic subset of a Stein manifold by a holomorphic action of a reductive complex Lie group $G$.
