Graded Mapping Cone Theorem, Multisecants and Syzygies
Let X be a reduced closed subscheme in P. As a slight generalization of property Np due to Green-Lazarsfeld, we can say that X satisfies property N2,p scheme-theoretically if there is an ideal I generating the ideal sheaf IX/Pn such that I is generated by quadrics and there are only linear syzygies up to p-th step (cf. [9], [10], [21] ). Recently, many algebraic and geometric results have been ...
متن کاملSYZYGIES OF CURVES AND THE EFFECTIVE CONE OF Mg
The aim of this paper is to describe a systematic way of constructing effective divisors on Mg having exceptionally small slope. In particular, these divisors provide a string of counterexamples to the Harris-Morrison Slope Conjecture (cf. [HMo]). In a previous paper [FP], we showed that the divisor K10 on M10 consisting of sections of K3 surfaces contradicts the Slope Conjecture on M10. Since ...

متن کاملRamsey's theorem and cone avoidance
It was shown by Cholak, Jockusch, and Slaman that every computable 2-coloring of pairs admits an infinite low2 homogeneous set H. We answer a question of the same authors by showing that H may be chosen to satisfy in addition C 6≤T H, where C is a given noncomputable set. This is shown by analyzing a new and simplified proof of Seetapun’s cone avoidance theorem for Ramsey’s theorem. We then ext...
متن کاملA cone theoretic Krein-Milman theorem in semitopological cones
In this paper, a Krein-Milman type theorem in $T_0$ semitopological cone is proved, in general. In fact, it is shown that in any locally convex $T_0$ semitopological cone, every convex compact saturated subset is the compact saturated convex hull of its extreme points, which improves the results of Larrecq.
