倾斜代数的AR序列的结构

Ringel和Happe3]给出了倾斜代数的连结序列。本文给出了落入H（AT）和落入Y（AT）的AR序列的结构；同时得到倾斜代数的以不可分投射模为终点的汇射和以不可分内射模为起点的源射的形式。这些连同序列确定了倾斜代数的AR箭图，而可以直接由相应的遗传代数的AR箭图得出。

The Structures of the AR Sequences of Tilted Algebras

In this paper,We give the forms of AR sequences of a tilted algebra with terms all belonging to x(A_T),or all belonging to y(A_T).The sink maps of a tilted algebra which end at the indecompos able projective modules and the source maps of starting at the indecomposable injective modules are also obtained.These results together with the connecting sequecnes given in 3] determine the AR quiver of the tilted algcbra,morever,this can be done directly from the AR quiver of the correspond ing hereditary algebra.
