Effective divisors on moduli spaces
The pseudo-effective cone Eff(X) of a smooth projective variety X is a fundamental, yet elusive invariant. On one hand, a few general facts are known: the interior of the effective cone is the cone of big divisors so, in particular, X is of general type if and only if KX ∈ int(Eff(X)); less obviously [4], a variety X is uniruled if and only if KX is not pseudo-effective and the dual of Eff(X) i...

متن کاملLefschetz pencils and divisors in moduli space
We study Lefschetz pencils on symplectic four-manifolds via the associated spheres in the moduli spaces of curves, and in particular their intersections with certain natural divisors. An invariant defined from such intersection numbers can distinguish manifolds with torsion first Chern class. We prove that pencils of large degree always give spheres which behave “homologically” like rational cu...
متن کاملKoszul Divisors on Moduli Spaces of Curves
In this paper we describe a general method of constructing special effective divisors on various moduli spaces using the syzygies of the parametrized objects. The method can be applied to a wide range of moduli problems with the property that the coarse moduli space has canonical singularities hence pluricanonical forms extend over any desingularization of the moduli space. Here we treat the ca...
متن کاملDistribution Laws of Pairs of Divisors
In this paper we study the distribution of pairs (d1, d2) of positive integers such that the product d1d2 divides a given integer n from a probabilistic point of view. The number of these pairs, denoted by τ3(n), is equal to the number of ways to write n as a product of three positive integers. To these pairs we associate a random vector taking the values ( (log d1)/(log n), (log d2)/(log n) ) ...
