我们以 Jordan 平面 R = kx, y/(xy − yx − y 2) 为例,研究代数的性质与其各种有限维模结构之间的关系。对任意维n得到的表示簇mod(R,n)的不可约分量的完整描述表明该簇是等维的。研究了非交换 Koszul (Golod-Shafarevich) 复形作为代数的 DG 代数解析 (NCCI) 的性质对表示空间结构的影响。结果表明,约旦飞机提供了RCI(代表性完全相交)的新例子。
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 = kx, 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 equidimen-sional. 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).
