Non-embeddability of certain classes of Levi flat manifolds
On the basis of a result of Barrett, we show that members of certain classes
of abstract Levi flat manifolds with boundary, whose Levi foliation contains a
compact leaf with contracting, flat holonomy, admit no embedding as a
hypersurface of a complex manifold.Comment: 8 pages, no figure
Bergman spaces of natural G-manifolds
Let G be a unimodular Lie group, X a compact manifold with boundary, and M
the total space of a principal bundle G--> M-->X so that M is also a strongly
pseudoconvex complex manifold. In this work, we show that if there exists a
point p in bM such that T_p(G) is contained in the complex tangent space of bM
at p, then the Bergman space of M is large. Natural examples include the gauged
G-complexifications of Heinzner, Huckleberry, and Kutzschebauch.Comment: 24 pages, no figure
Infinitesimal and local rigidity of mappings of CR manifolds
A holomorphic mapping between two real-analytic CR manifolds and
is said to be locally rigid if any other holomorphic map
which is close enough to is obtained by composing with suitable
automorphisms of and . With the aim of reducing the local rigidity
problem to a linear one, we provide sufficient infinitesimal conditions.
Furthermore we study some topological properties of the action of the
automorphism group on the space of nondegenerate mappings from to
