上三角微分分次代数的导等价

Derived Equivalences of Upper Triangular Differential Graded Algebras

Daniel Maycock

摘要:

本文将上三角形矩阵环的一个结果推广到上三角形矩阵DGA的情形。上三角形矩阵DGA具有形式(R,S,M),其中R和S是微分分次代数,M是DG-左-R-右-S-双模.本文证明了在DG-模M上,在一定条件下,若存在一个DG-R-模X,由此可建立导出范畴D(R),则上三角形矩阵DGA(R,S,M)与(S,M ',R')之间存在一个导出等价,其中DG-双模M'是由M和X得到的,R'是X的一个K-投射分解的自同态DGA.

英文摘要:

This paper generalises a result for upper triangular matrix rings to the situation of upper triangular matrix DGA's. An upper triangular matrix DGA has the form (R,S,M) where R and S are differential graded algebras and M is a DG-left-R-right-S-bimodule. We show that under certain conditions on the DG-module M and with the existance of a DG-R-module X, from which we can build the derived category D(R), that there exists a derived equivalence between the upper triangular matrix DGAs (R,S,M) and (S,M',R'), where the DG-bimodule M' is obtained from M and X and R' is the endomorphism DGA of a K-projective resolution of X.
