摘要
给出了几乎有限表现维数的定义,研究了几乎有限表现维数的性质,得出了一些特殊环的几乎有限表现维数,且揭示了几乎有限表示维数与有限表现维数的关系.
In this paper, the definition of almost fmitely-preeented dimension is given, properties of almost finitely-presented dimension are studied, almost finitely-preeented dimensions of some special ring are obtained, and relations between almost finitely-presented dimension and finitely-presented dimension are shown.
