由两项倾斜复形产生的倾斜模

Tilting modules arising from two-term tilting complexes

Hiroki Abe

摘要:

我们证明了Artin代数上的每一个双项倾斜复形都有一个倾斜模在某个因子代数上作为同调群。另外,我们还确定了这样一个同调群的自同态代数,它是作为两项倾斜复形的自同态代数的一个因子代数给出的。因此,每一个由两项倾斜复形给出的Artin代数之间的导出等价都诱导出相应的因子代数之间的导出等价。

英文摘要:

We show that every two-term tilting complex over an Artin algebra has a tilting module over a certain factor algebra as a homology group. Also, we determine the endomorphism algebra of such a homology group, which is given as a certain factor algebra of the endomorphism algebra of the two-term tilting complex. Thus, every derived equivalence between Artin algebras given by a two-term tilting complex induces a derived equivalence between the corresponding factor algebras.
