起波澜

Programmbeispiele aus der Mathematik, homotopy classes of DG-Lie algebras, each one of them controlling this above deformation problem: the first homotopy type is described in terms of the projective model structure on the category of diagrams of differential graded algebras, the others in terms of the Reedy model structure on truncate

Programmieren von Taschenrechnernes. In particular, we consider the natural embedding of the space of complete quadrics into the space of complete collineations and we observe that their birational geometry, from the point of view of Mori theory, fully determines each other. When two varieties are related in this way, we call them

A Note on Severi Varieties of Nodal Curves on Enriques Surfaces,let ..(.) be the Severi variety of irreducible .-nodal curves in |.|. We denote by . : . → . the universal covering of .. In this note we compute the dimensions of the irreducible components . of ..(.). In particular we prove that, if . is the curve corresponding to a general element [.] of . , then

In particular, we consider the natural embedding of the space of complete quadrics into the space of complete collineations and we observe that their birational geometry, from the point of view of Mori theory, fully determines each other.

Examples of Irreducible Symplectic Varieties,uville-Bogomolov decomposition theorem. There are several singular analogues of irreducible symplectic manifolds, in particular in the context of compact Kähler orbifolds, and in the context of normal projective varieties with canonical singularities. In this paper we will collect their definitions,
