Moishezon Manifolds
Marco Andreatta
Let X be a compact Moishezon manifold which becomes projective after blowing up a smooth subvariety . We assume also that there exists a proper map onto a…
A view on contractions of higher dimensional varieties
Marco Andreatta, Jaroslaw A. Wiśniewski
In this paper we discuss some recent results about extremal contractions of complex algebraic varieties. These are proper surjective maps, , of normal variet…
On Contractions of smooth varieties
Marco Andreatta, Jarosław A. Wiśniewski
Let $\f: X \ra Z$ be a proper surjective map from a smooth complex manifold onto a normal variety . If $\f$ has connected fibers and is $\f$-ample then $\f$ is called…
Contractions on a manifold polarized by an ample vector bundle
M. Andreatta, M. Mella
A complex manifold of dimension together with an ample vector bundle on it will be called a {\sf generalized polarized variety}. The adjoint bundle of the pair …
A note on non-vanishing and applications
Marco Andreatta, Jarosław A. Wiśniewski
Let be a normal variety over the field of complex numbers with log terminal singularities and the canonical divisor being -Gorenstein. Assume that is an ampl…
