In the present paper, we associate the techniques of the Lewy-Pinchuk reflection
principle with the Behnke-Sommer continuity principle. Extending a so-called reflection function to a parameterized congruence of Segre varieties, we are led to
studying the envelope of holomorphy of a certain domain covered by a smooth Levi-flat
“hat”. In our main theorem, we show that every -smooth CR diffeomorphism
between two globally minimal real analytic hypersurfaces in () is real analytic at every point...
We present a large class of homogeneous 2-nondegenerate CR-manifolds , both of
hypersurface type and of arbitrarily high CR-codimension, with the following property: Every CR-equivalence
between domains , in extends to a global real-analytic CR-automorphism of . We show that this class contains -orbits in Hermitian symmetric spaces of compact type, where is a real form of the complex Lie group and has an open orbit that is a bounded symmetric domain of tube type.
For large classes of complex Banach spaces (mainly operator spaces) we consider orbits of finite rank elements under the group of linear isometries. These are (in general) real-analytic submanifolds of infinite dimension but of finite CR-codimension. We compute the polynomial convex hull of such orbits explicitly and show as main result that every continuous CR-function on has a unique extension to the polynomial convex hull which is holomorphic in a certain sense. This generalizes to infinite...
Let M be a generic CR submanifold in , m = CR dim M ≥ 1, n = codim M ≥ 1, d = dim M = 2m + n. A CR meromorphic mapping (in the sense of Harvey-Lawson) is a triple , where: 1) is a ¹-smooth mapping defined over a dense open subset of M with values in a projective manifold Y; 2) the closure of its graph in defines an oriented scarred ¹-smooth CR manifold of CR dimension m (i.e. CR outside a closed thin set) and 3) in the sense of currents. We prove that extends meromorphically to a wedge...
The rigidity properties of the local invariants of real algebraic Cauchy-Riemann structures imposes upon holomorphic mappings some global rational properties (Poincaré 1907) or more generally algebraic ones (Webster 1977). Our principal goal will be to unify the classical or recent results in the subject, building on a study of the transcendence degree, to discuss also the usual assumption of minimality in the sense of Tumanov, in arbitrary dimension, without rank assumption and for holomorphic...
