二次单项代数的奇异范畴

The singularity category of a quadratic monomial algebra

Xiao-Wu Chen

摘要:

我们利用奇异等价之间的阿廷代数,这是从某些函子之间的稳定的模块范畴。这样的函子称为前三角等价。我们构造了连接二次单项代数上的稳定模范畴和根式为零的代数上的稳定模范畴的两个预三角等价。因此,我们得到了两个代数之间的显式奇异等价。

英文摘要:

We exploit singular equivalences between artin algebras, that are induced from certain functors between the stable module categories. Such functors are called pre-triangle equivalences. We construct two pre-triangle equivalences connecting the stable module category over a quadratic monomial algebra and the one over an algebra with radical square zero. Consequently, we obtain an explicit singular equivalence between the two algebras.
