Combinatorial Aspects of Exceptional Sequences on (rational) Surfaces
We investigate combinatorial aspects of exceptional sequences in the derived category of coherent sheaves on smooth and complete algebraic surfaces with pg = q = 0. We show that to any such sequence there is canonically associated a complete toric surface whose torus fixpoints are either smooth or cyclic T-singularities (in the sense of Wahl) of type 1 r2 (1, kr − 1). We also show that any exce...
متن کاملExamples for Exceptional Sequences of Invertible Sheaves on Rational Surfaces
The purpose of this note is to give a survey on the results of joint work with Lutz Hille [HP08] and to provide some explicit examples. The general problem addressed in [HP08] is to understand the derived category of coherent sheaves on an algebraic variety (for an introduction and overview on derived categories over algebraic varieties we refer to [Huy06]; see also [Bri06]). An important appro...
متن کاملExceptional Covers and Bijections on Rational Points
We show that if f : X −→ Y is a finite, separable morphism of smooth curves defined over a finite field Fq, where q is larger than an explicit constant depending only on the degree of f and the genus of X , then f maps X(Fq) surjectively onto Y (Fq) if and only if f maps X(Fq) injectively into Y (Fq). Surprisingly, the bounds on q for these two implications have different orders of magnitude. T...
متن کاملOn Complex Surfaces Diffeomorphic to Rational Surfaces
The first major step in proving that every complex surface diffeomorphic to a rational surface is rational was Yau’s theorem [40] that every complex surface of the same homotopy type as P is biholomorphic to P. After this case, however, the problem takes on a different character: there do exist nonrational complex surfaces with the same oriented homotopy type as rational surfaces, and the issue...
متن کاملExceptional Covers of Surfaces
Consider a finite morphism f : X → Y of smooth, projective varieties over a finite field F. Suppose X is the vanishing locus in PN of r forms of degree at most d. We show that there is a constant C depending only on (N, r, d) and deg( f ) such that if |F| > C, then f (F) : X(F) → Y(F) is injective if and only if it is surjective.
