چکیده
Let X be an n-dimensional normal projective variety with terminal, Gorenstein, Qfactorial singularities. Let L be an ample line bundle on X . Let t be the nefvalue of ðX ;LÞ. Then we classify ðX ;LÞ, describing the structure of the nefvalue morphism of ðX ;LÞ, when t satisfies n k < t < n k þ 1 and nd 2k 3, kd 4. In the smooth case, we discuss the case n 1⁄4 2k 4, kd 5, as well.

Simulation of Surface Plasmon Excitation in a Plasmonic Nano-Wire Using Surface Integral Equations
In this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. First, integral equationsgoverning unknown fields on the surface is obtained based on Stratton-Cho surface integral equations. Then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. It is shown that in scatter...
متن کاملPrincipally Polarized Ordinary Abelian Varieties over Finite Fields
Deligne has shown that there is an equivalence from the category of ordinary abelian varieties over a finite field A: to a category of Z-modules with additional structure. We translate several geometric notions, including that of a polarization, into Deligne's category of Z-modules. We use Deligne's equivalence to characterize the finite group schemes over k that occur as kernels of polarizatio...
متن کاملTheta-regularity of Curves and Brill–noether Loci
We provide a bound on the Θ-regularity of an arbitrary reduced and irreducible curve embedded in a polarized abelian variety in terms of its degree and codimension. This is an “abelian” version of Gruson–Lazarsfeld–Peskine’s bound on the Castelnuovo–Mumford regularity of a non-degenerate curve embedded in a projective space. As an application, we provide a Castelnuovo type bound for the genus o...

By means of analytic methods the quasi-projectivity of the moduli space of algebraically polarized varieties with a not necessarily reduced complex structure is proven including the case of non-uniruled polarized varieties.

Let G be a finite group. For each integral representation ρ of G we consider ρ−decomposable principally polarized abelian varieties; that is, principally polarized abelian varieties (X,H) with ρ(G)−action, of dimension equal to the degree of ρ, which admit a decomposition of the lattice for X into two G−invariant sublattices isotropic with respect to IH , with one of the sublattices ZG−isomorph...
