摘要
本文研究单项代数上模的同调性质.应用Huisgen-Zimmermann的著名结果,分别给出了由一条道路生存的投射模及好模存在的充分条件.
In this article, we study the homological properties of modules over a monomial algebra. By using Huisgen-Zimmermann's famous result, we establish sufficient conditions for the existence of projective modules generated by a path and nice modules, respectively.
