On the S2-fication of Some Toric Varieties
نویسنده
چکیده
Let X be an algebraic variety, the set of points where X is not Cohen-Macaulay is the Non-CohenMacaulay locus, this set was study in [1]. Macaulayfication is an analogous operation to resolution of singularities and was considered in [7] where the main theorem of Macaulayfication is given. For any affine semigroup (without torsion) S ⊂ IN let G(S) be the subgroup of ZZ generated by S and S̄ be the saturation of S inside G(S), that is

Intersection complexes of fans and toric varieties
In [GM2], Goresky and MacPherson defined and constructed intersection complexes for topological pseudomanifolds. The complexes are defined in the derived category of sheaves of modules over a constant ring sheaf. Since analytic spaces are of this category, algebraic varieties defined over C have intersection complexes. The intersection complex of a given variety has a variation depending on a s...
متن کامل2 00 2 Notes on toric varieties Helena Verrill
These notes survey some basic results in toric varieties over a field F , with examples and applications. A computer algebra package (written by the author) is described which deals with both affine and projective toric varieties in any number of dimensions (written in both MAGMA [MAGMA] and GAP [GAP]). Among other things, the package implements the desingularization procedure, constructs some ...
متن کاملToric ideals, real toric varieties, and the moment map
This is a tutorial on some aspects of toric varieties related to their potential use in geometric modeling. We discuss projective toric varieties and their ideals, as well as real toric varieties and the moment map. In particular, we explain the relation between linear precision and the moment map.

متن کاملOn the Hodge structure of degenerating hypersurfaces in toric varieties
We introduce an algebraic method for describing the Hodge filtration of degenerating hypersurfaces in projective toric varieties. For this purpose, we show some fundamental properties of logarithmic differential forms on proper equivariant morphisms of toric varieties.
