An existence theorem for stationary discs in almost complex manifolds

Andrea Spiro, Alexandre Sukhov

An existence theorem for stationary discs of strongly pseudoconvex domains in almost complex manifolds is proved. More precisely, it is shown that, for all points of a suitable nei…

Homogeneous toric bundles with positive first Chern class

Fabio Podesta', Andrea Spiro

A simple algebraic characterization of the Fano manifolds in the class of homogeneous toric bundles over a flag manifold is provided in terms of symplectic data.

Cohomology groups for Lagrange complexes that are invariant under a pseudogroup of local transformations

Andrea Spiro

This paper has been withdrawn by the author due to a crucial error in formula 4.12.r

Explicit construction of a Chern-Moser connection for CR manifolds of codimension two

Gerd Schmalz, Andrea Spiro

In the present paper we suggest an explicit construction of a Cartan connection for an elliptic or hyperbolic CR manifold M of dimension six and codimension two, i.e. a pair (P, w)…

Running after a new Kaehler-Einstein metric

Fabio Podesta', Andrea Spiro

We deal with compact Kaehler manifolds M which are acted on by a semisimple compact Lie group G of isometries with codimension one regular orbits. We provide an explicit descriptio…

The Ricci tensor of an almost homogenous Kaehler manifold

Andrea Spiro

We determine an explicit expression for the Ricci tensor of a K-manifold, that is of a compact Kaehler manifold M with vanishing first Betti number, on which a semisimple group G o…
