本文对线性定向的A-n型图的完备路代数进行了倾斜模和余倾斜模的分类。这个分类问题在某些结合代数上的余倾斜模的分类中自然出现(Pacific J.Math.211(2003)41-60)。所有的倾斜和cotilting模块的集合的组合描述的Stasheff associahedra。
Tilting and cotilting modules are classified for the completed path algebra of a quiver of type A ̃nwith linear orientation. This classification problem arises naturally in the classification of cotilting modules over certain associative algebras (Pacific J. Math. 211 (2003) 41–60). The combinatorics of the collection of all tilting and cotilting modules is described in terms of Stasheff associahedra.
