导出微分分次范畴的Nakayama函子

The Nakayama Functor of Deriving DG Category

设A是域k上的DG范畴,B.Keller定义了微分分次范畴Dif A的DG函子ν。在定义了Dif A的DG函子的基础上,证明了ν和是HA的正和函子,且ν和诱导了DA的正和函子Lν和R。

Let be a DG category over a field, B.Keller defined the Nakayama functor νof Dif .In the pa-per , on the basis of the definition of ν-, which is a dg functor of Dif , thatνand ν-are exact functors of is proved, and both functors induce the derived triangulated exact functors Lνand Rν-of .
