O ct 2 00 4 COMPLETE INTERSECTION LATTICE
نویسندگان
چکیده
In this paper we completely characterize lattice ideals that are complete intersections or equivalently complete intersections finitely generated semigroups of ZZn ⊕ T with no invertible elements, where T is a finite abelian group. We also characterize the lattice ideals that are set-theoretic complete intersections on binomials.

Let Mg,2 be the moduli space of curves of genus g with a level2 structure. We prove here that there is always a non hyperelliptic element in the intersection of four thetanull divisors in M6,2. We prove also that for all g > 3, each component of the hyperelliptic locus in Mg,2 is a connected component of the intersection of g − 2 thetanull divisors.

In the last several years, tightly coupled PC clusters have become widely applied, cost effective resources for lattice gauge computations. This paper discusses the practice of building such clusters, in particular balanced design requirements. I review and quantify the improvements over time of key performance parameters and overall price to performance ratio. Applying these trends and technol...

We analyze zero modes of the Dirac operator for SU(2) lattice gauge theory. We find that the zero modes are strongly localized in all 4 directions. The position of these lumps depends on the boundary conditions we use for the Dirac operator. We compare periodic boundary conditions and anti-periodic boundary conditions and find that the position of the zero modes jumps for about one third of the...

We calculate the electromagnetic form factor of the pion in quenched lattice QCD. The non-perturbatively improved Sheikoleslami-Wohlert lattice action is used together with the consistently O(a) improved current. We calculate the pion form factor for masses down to mπ = 360 M eV , extract the charge radius, and extrapolate toward the physical pion mass. In the second part, we discuss results fo...
