Effective Non-vanishing of Asymptotic Adjoint Syzygies
Effective Non-vanishing Asymptotic Adjoint Syzygies Algebraic Geometry
2012/4/17
The purpose of this paper is to establish an effective non-vanishing theorem for the syzygies of an adjoint-type line bundle on a smooth variety, as the positivity of the embedding increases. Our purp...

Abstract: Let $C=Z(f)$ be a reduced plane curve of degree $6k$, with only nodes and ordinary cusps as singularities. Let $I$ be the ideal of the points where $C$ has a cusp. Let $\oplus S(-b_i)\to \op...
We prove new results on projective normality, normal presentation and higher syzygies for a surface of general type X embedded by adjoint line bundles Lr = K + rB, where B is a base
point free, ample...
We study the linear syzygies of a homogeneous ideal I ⊆ S =Symk(V ), focussing on the graded betti numbers bi,i+1 = dimk Tori(S/I, k)i+1.

We develop a systematic and efficient method of counting single-trace and multi-trace BPS operators for world-volume gauge theories of N D-brane probes, for both N → ∞ and finite N. The techniques are...
