Components of the Stack of Torsion-Free Sheaves of Rank 2 on Ruled Surfaces
Let S be a ruled surface without sections of negative self-intersection. We classify the irreducible components of the moduli stack of torsion-free sheaves of rank 2 sheaves on S. We also classify the irreducible components of the Brill-Noether loci in Hilb (P × P) given by W 0 N (D) = {[X ] | h1(IX(D)) ≥ 1} for D an effective divisor class. Our methods are also applicable to P giving new proof...
متن کاملEmpty Real Enriques Surfaces and Enriques-einstein-hitchin 4-manifolds
N. Hitchin [H] proved that the Euler characteristic χ(E) and signature σ(E) of a compact orientable 4-dimensional Einstein manifold E satisfy the inequality |σ(E)| 6 2 3χ(E), the equality holding only if either E is flat or the universal covering X of E is a K3-surface and π1(E) = 1, Z/2, or Z/2× Z/2. In the latter cases, E is a K3-surface if π1 = 1, an Enriques surface if π1 = Z/2, or the quot...
متن کاملHitchin systems in N = 2 field theory
This note is a short review of the way Hitchin systems appear in four-dimensional N = 2 supersymmetric field theory. The literature on the Hitchin system and its role in quantum field theory is a vast one. Restricting attention just to the role of Hitchin systems in N = 2 supersymmetric field theory (thus neglecting such fascinating topics as T-duality on the Hitchin fibration and its relation ...
متن کاملHitchin Functionals in N = 2 Supergravity
We consider type II string theory in space-time backgrounds which admit eight supercharges. Such backgrounds are characterized by the existence of a (generically nonintegrable) generalized SU (3)×SU (3) structure. We demonstrate how the corresponding ten-dimensional supergravity theories can in part be rewritten using generalised O(6, 6)covariant fields, in a form that strongly resembles that o...
متن کاملRank aggregation in cyclic sequences
In this paper we propose the problem of finding the cyclic sequence which best represents a set of cyclic sequences. Given a set of elements and a precedence cost matrix we look for the cyclic sequence of the elements which is at minimum distance from all the ranks when the permutation metric distance is the Kendall Tau distance. In other words, the problem consists of finding a robust cyclic r...
