形式矩阵环上投射模的对偶基及其应用
The Dual Basis of Some Projective Modules Over a Formal Matrix Ring and Its Application
【摘要】 对偶基是研究投射模内部刻画的重要工具,本文系统研究了形式矩阵环F上投射模的对偶基,应用对偶基给出了形式矩阵环上投射模的内部刻画,得到了F模存在投射盖的充要条件.
【Abstract】 The dual basis is an important tool for studying projective module internal structure.In this paper,the projective module over the formal matrix rings are characterized by the dual basis.Also the sufficient and necessary conditions are found for an F module to admit a projective cover.
