Jordan平面的表示空间

Representation spaces of the Jordan plane

Natalia K. Iyudu

摘要:

以Jordan平面$R=k<x,y>/ (xy-yx-y^2)$为例,研究了代数的性质与其有限维模结构的变种之间的关系。对任意维数$n$得到的表示簇$mod (R,n)$的不可约分量的完整描述,证明了该簇是等维的.研究了非交换Koszul(Golod-Shafarevich)复形是代数的DG-代数分解(NCCI)的性质对表示空间结构的影响.证明了若当平面是代表性完全相交的一个新例子。

英文摘要:

We investigate relations between the properties of an algebra and its varieties of finite-dimensional module structures, on the example of the Jordan plane $R=k<x,y>/ (xy-yx-y^2)$. Complete description of irreducible components of the representation variety $mod (R,n)$ obtained for any dimension $n$, it is shown that the variety is equidimensional. The influence of the property of the non-commutative Koszul (Golod-Shafarevich) complex to be a DG-algebra resolution of an algebra (NCCI), on the structure of representation spaces is studied. It is shown that the Jordan plane provides a new example of RCI (representational complete intersection).
