1) n-presented dimension
n-表现维数
1.
In this thesis, we mainly investigate n-presented dimensions of rings and modules, and relations between the dimensions and other homological dimensions.
本论文研究了模与环的n-表现维数及与其他维数的关系,给出了右n-凝聚环的一种分类,并得到了环的右总体维数一个刻画。

Using n-presented modules, introduce the concepts of n-presented dimensions FPnd(M) and FPnD(R) of a module M and a ring R, obtain some relations among FPnd(M),fd(M) and pd(M),and then characterize a right n-coherent ring R, that is,R is right coherent if and only if FPnd(M)=FPn+1d(M)for each right R-module M.
利用n-表现模定义了模M与环R的n-表现维数FPnd(M)与FPnD(R),给出了FPnd(M),fd(M)及pd(M)之间的关系,刻画了右n-凝聚环,即R为右n-凝聚环当且仅当对于任意右R-模M,均有FPnd(M)=FPn+1d(M)。
2) n-copresented dimension
n-余表现维数
1.
Using n-copresented modules, we introduce the concepts of n-copresented dimension COPn dM of a module M and characterize a right n-cocoherent ring R, that is, R is right n-cocoherent if and only if COPn d(M) = COPn+1d(M) for each right R-module M.
利用n-余表现模定义了模M的n-余表现维数COPnd(M),刻画了右n-余凝聚环,即R为右n-余凝聚环当且仅当对于任意右R-模M,均有COPnd(M)=COPn+1d(M),并研究了在环扩张下模的n-余表现维数的若干关系式。
