复形的Kustin-Miller非投影

Kustin-Miller unprojection with complexes

Stavros Papadakis

摘要:

Kustin-Miller非投射的一个主要成分,如在(S。Papadakis和M. Reid,Kustin-Miller unprojection without complex,math.AG/0011094)是模Hom_R(I,\om_R),其中R是局部Gorenstein环,I是R/I Gorenstein的余维1理想.我们证明了一种方法,计算它在一个相对的设置使用决议。我们提出三个应用。在第一部分中,我们推广了(F。Catanese等人,曲线和曲面的嵌入,Nagoya Math.J.154(1999),185-220)。第二个和第三个是关于汤姆和杰里,两个家庭的Gorenstein余维四环与9 x16的决议。

英文摘要:

A main ingredient for Kustin-Miller unprojection, as developed in (S. Papadakis and M. Reid, Kustin-Miller unprojection without complexes, math.AG/0011094), is the module Hom_R(I, \om_R), where R is a local Gorenstein ring and I a codimension one ideal with R/I Gorenstein. We prove a method of calculating it in a relative setting using resolutions. We give three applications. In the first we generalise a result of (F. Catanese et al., Embeddings of curves and surfaces, Nagoya Math. J. 154 (1999), 185-220). The second and the third are about Tom and Jerry, two families of Gorenstein codimension four rings with 9x16 resolutions.
