摘要

本文给出了编码不可分解对象和它们之间的正扩展的温和代数有界派生范畴的一个约束模型。然后使用该模型对线性方向An的d期淤积物进行计数，恢复了用Pfaff-Fuss-Catalan数计数的结果。

A restricted model for the bounded derived category of gentle algebras

We present a restricted model for the bounded derived category of gentle algebras that encodes the indecomposable objects and positive extensions between them. The model is then used to count the number of d-term silting objects for linearly oriented

A_{n}

, recovering the result that they are counted by the Pfaff-Fuss-Catalan numbers.
