Surfaces with Big Anticanonical Class
Mori dream spaces were introduced by Y. Hu and S. Keel [9]; they are natural generalizations of toric varieties. We recall the definition. Let X be a Q-factorial and normal projective variety, such that Pic(X)⊗Z Q = N(X). Let D1, . . . , Dr be a collection of divisors that give a basis for Pic(X), and whose affine hull contains the pseudoeffective cone. The Cox ring of X is the multi-graded sec...
متن کاملOn Fundamental Groups of Class VII Surfaces
The purpose of this note is to obtain a restriction on the fundamental groups of nonelliptic compact complex surfaces of class VII in Kodaira’s classification [9]. We recall that these are the compact complex surfaces with first Betti number one and no nonconstant meromorphic functions. This seems to be the class of compact complex surfaces whose structure is least understood. The first and sim...
متن کاملAnticanonical Rational Surfaces
A determination of the fixed components, base points and irregularity is made for arbitrary numerically effective divisors on any smooth projective rational surface having an effective anticanonical divisor. All of the results are proven over an algebraically closed field of arbitrary characteristic. Applications, to be treated in separate papers, include questions involving: points in good pos...
متن کاملSeshadri Constants on Rational Surfaces with Anticanonical Pencils
We provide an explicit formula for Seshadri constants of any polarizations on rational surfaces X such that dim |−KX | ≥ 1. As an application, we discuss relationship between singularities of log del Pezzo surfaces and Seshadri constants of their anticanonical divisors. We also give some remarks on higher order embeddings of del Pezzo surfaces.
متن کاملNumerically Calabi-yau Orders on Surfaces
This is part of an ongoing program to classify maximal orders on surfaces via their ramification data. Del Pezzo orders and ruled orders have been classified in [6, 4] and [2]. In this paper, we classify numerically CalabiYau orders which are the noncommutative analogues of surfaces of Kodaira dimension zero. Throughout, all objects and maps are assumed to be defined over some algebraically clo...
