Projective Surfaces with Many Nodes

چکیده
We prove that a smooth projective complex surface X, not necessarily minimal, contains h(X) − 1 disjoint (−2)-curves if and only if X is isomorphic to a relatively minimal ruled rational surface F2 or P or a fake projective plane. We also describe smooth projective complex surfaces X with h(X) − 2 disjoint (−2)-curves.

N ov 2 00 6 PROJECTIVE MODELS OF K 3 SURFACES WITH AN EVEN SET
The aim of this paper is to describe algebraic K3 surfaces with an even set of rational curves or of nodes. Their minimal possible Picard number is nine. We completely classify these K3 surfaces and after a carefull analysis of the divisors contained in the Picard lattice we study their projective models, giving necessary and sufficient conditions to have an even set. Moreover we investigate th...

متن کاملSurfaces via Almost - Primes
Based on the result on derived categories on K3 surfaces due to Mukai and Orlov and the result concerning almost-prime numbers due to Iwaniec, we remark the following facts: (1) For any given positive integer N , there are N (mutually non-isomorphic) projective complex K3 surfaces such that their Picard groups are not isomorphic but their transcendental lattices are Hodge isometric, or equivale...
متن کاملKähler–einstein Metrics on Log Del Pezzo Surfaces in Weighted Projective 3–spaces
A log del Pezzo surface is a projective surface with quotient singularities such that its anticanonical class is ample. Such surfaces arise naturally in many different contexts, for instance in connection with affine surfaces [Miyanishi81], moduli of surfaces of general type [Alexeev94], 3 and 4 dimensional minimal model program [Alexeev93]. They also provide a natural testing ground for existe...
متن کاملModuli of Twisted Orbifold Sheaves
We study stacks of slope-semistable twisted sheaves on orbisurfaces with projective coarse spaces and prove that in certain cases they have many of the asymptotic properties enjoyed by the moduli of slope-semistable sheaves on smooth projective surfaces.
