Regularity of infinitesimal automorphisms of involutive structures

Bernhard Lamel, Nicholas Braun Rodrigues

In this paper, we prove that infinitesimal automorphisms of an involutive structure are smooth. For this, we build a regularity theory for sections of vector bundles over an involu…

Approximation of pseudohermitian structures via embeddings into spheres

Hendrik Herrmann, Chin-Yu Hsiao, Bernhard Lamel

Let be a compact strictly pseudoconvex CR manifold which is CR embeddable into the complex Euclidean space. We show that can be approximated in $\mathscr{…

A sphericity criterion for strictly pseudoconvex hyper surfaces in via invariant curves

Florian Bertrand, Giuseppe Della Sala, Bernhard Lamel

We prove that if every chain on a strictly pseudoconvex hypersurface in coincides with the boundary of a stationary disc, then is locally spherical.

Intrinsic complexification of real-analytic varieties

Bernhard Lamel, Jiri Lebl

We introduce a framework for Segre varieties for singular real-analytic subvarieties of a complex space and utilize it to study the intrinsic complexifications of these subvarietie…

Holomorphic vector fields with real integral manifolds

Martin Kolář, Ilya Kossovskiy, Bernhard Lamel

We classify singular holomorphic vector fields in two-dimensional complex space admitting a (Levi-nonflat) real-analytic invariant 3-fold through the singularity. In this way, we c…

Regularity of CR maps into uniformly pseudoconvex hypersurfaces and applications to proper holomorphic maps

Josef Greilhuber, Bernhard Lamel

We study regularity properties of CR maps in positive codimension valued in pseudoconvex manifolds which carry a nontrivial Levi foliation. We introduce an invariant which can be u…
