摘要
设τ=(T,F)是遗传挠理论,提出了τ-C 11模的概念,它是τ-C 1模和C 11模的推广.讨论了τ-C 1模,τ-C 11模和τ-FI-extending模之间的关系,给出了τ-C 11模的等价条件.进而,研究了τ-C 11模关于直和因子,τ-稠密子模的封闭性.
Letτ=(T,F)be a hereditary torsion theory.In this paper,the concept ofτ-C 11 module is introduced,which is a generalization ofτ-C 1 and C 11 module.The relations amongτ-C 1 modules,τ-C 11 modules andτ-FI-extending modules are discussed,and some equivalent conditions ofτ-C 11 module are given.Moreover,the closure ofτ-C 11 modules with respect to direct summand andτ-dense submodules are discussed.
