一类特殊的Koszul Calabi-Yau DG代数
A Special Class of Koszul Calabi-Yau DG Algebras
假设一个连通上链DG代数A的基分次代数A#或者同调分次代数H（A）是由一次元素x，y生成的代数k<x，y>/（xy+yx）. 本文证明A是Koszul Calabi-Yau DG代数.
It is proved in this paper that a connected cochain DG algebra A is a Koszul Calabi-Yau DG algebra if either its cohomology graded algebra H(A) or its underlying graded algebra A# is the algebra k<x,y>/(xy+yx) generated by degree 1 elements x,y.
