Uniruled Surfaces of General Type
نویسنده
چکیده
We give a systematic construction of uniruled surfaces in positive characteristic. Using this construction, we find surfaces of general type with non-trivial global vector fields, surfaces with arbitrarily non-reduced Picard schemes as well as surfaces with inseparable canonical maps. In particular, we show that some previously known pathologies are not sporadic but exist in abundance.

Smooth Projective Symmetric Varieties with Picard Number Equal to One
We classify the smooth projective symmetric varieties with Picard number equal to one. Moreover we prove a criterion for the smoothness of the simple (normal) symmetric varieties whose closed orbit is complete. In particular we prove that a such variety X is smooth if and only if an appropriate toric variety contained in X is smooth. A Gorenstein normal algebraic variety X over C is called a Fa...
متن کاملOn Varieties Which Are Uniruled by Lines
Using the ♯-minimal model program of uniruled varieties we show that for any pair (X,H) consisting of a reduced and irreducible variety X of dimension k ≥ 3 and a globally generated big line bundle H on X with d := H and n := h(X,H) − 1 such that d < 2(n− k)− 4, then X is uniruled of H-degree one, except if (k, d, n) = (3, 27, 19) and a ♯-minimal model of (X,H) is (P3,OP3(3)). We also show that...
متن کاملContact hypersurfaces in uniruled symplectic manifolds always separate
We observe that nonzero Gromov-Witten invariants with marked point constraints in a closed symplectic manifold imply restrictions on the homology classes that can be represented by contact hypersurfaces. As a special case, contact hypersurfaces must always separate if the symplectic manifold is uniruled. This removes a superfluous assumption in a result of G. Lu [Lu00], thus implying that all c...
متن کاملFoliations with vanishing Chern classes
In this paper we aim at the description of foliations having tangent sheaf TF with c1(TF) = c2(TF) = 0 on non-uniruled projective manifolds. We prove that the universal covering of the ambient manifold splits as a product, and that the Zariski closure of a general leaf of F is an Abelian variety. It turns out that the analytic type of the Zariski closures of leaves may vary from leaf to leaf. W...
متن کاملEvery Orientable Seifert 3-manifold Is a Real Component of a Uniruled Algebraic Variety
We show that any orientable Seifert 3-manifold is diffeomorphic to a connected component of the set of real points of a uniruled real algebraic variety, and prove a conjecture of János Kollár.
