摘要
受补子模、τ-补子模等概念的启发,提出了t-补子模的概念,讨论了t-补子模、τ-补子模和补子模之间的关系,给出了t-补子模、τ-补子模和补子模是不同概念的例子,研究了t-补子模的若干性质.进而,讨论了两个子模互为t-补的充要条件,并证明了t-补子模的传递性.
Inspired by the concepts of complement submodule andτ-complement submodule,the concept of t-complement submodule is introduced.The relations among complement submodules,τ-complement submodules and t-complement submodules are discussed,examples are given to show that they are different concepts,and some properties of t-complement submodules are studied.Moreover,the necessary and sufficient conditions for two submodules to be t-complement of each other are investigated,and also the transitivity property for t-complement submodules are proved.
