有界导出范畴中Auslander-Reiten分支的例子

Examples of Auslander-Reiten components in the bounded derived Category

Sarah Scherotzke

摘要:

通过对复形范畴中某些类型的不可约映射进行分类,得到了有限维代数的有界导出范畴的Auslander-Reiten分支有欧氏树类的一个必要条件.这一结果表明,只有100多个Auslander-Reiten组件与欧几里德树类移动。还直接计算了某些Nakayama类的Auslander-Reiten代数,并证明了它们是分段遗传的。最后,给出了$\Z[A_{\infty}]$ -分量出现在Auslander-Reiten图中的条件,推广了\cite{W}中的一个结果.

英文摘要:

We deduce a necessary condition for Auslander-Reiten components of the bounded derived category of a finite dimensional algebra to have Euclidean tree class by classifying certain types of irreducible maps in the category of complexes. This result shows that there are only finitely many Auslander-Reiten components with Euclidean tree class up to shift. Also the Auslander-Reiten quiver of certain classes of Nakayama are computed directly and it is shown that they are piecewise hereditary. Finally we state a condition for $\Z[A_{\infty}]$-components to appear in the Auslander-Reiten quiver generalizing a result in \cite{W}.
