摘要
给出相对伪k-内射半模的概念,并刻画了相对伪k-内射半模的相关性质。主要给出了以下结论:N是相对M伪k-内射半模当且仅当对任意的s∈S=K-EndR(M),HomR(M,N)s{f∈HomR(M,N)|ker(f)=ker(s)};相对M伪k-内射半模的任意直和项仍然是相对M的伪k-内射半模;如果N是相对M的伪k-内射半模,则N对于相对M的任意k-子半模A而言,也是A伪k-内射半模。
The concept of pseudo k-injective semimodules relative to M is given on this paper. Several properties of relative pseudo k-injective semimodules are investigated. The following are main results: N is pseudo k-injective semimodule relative to M if and only if for any element s ∈ S = K-EndR( M),HomR( M,N) s{ f∈HomR( M,N) | ker( f) = ker( s) }; any direct summand of pseudo kinjective semimodule relative to M is still pseudo k-injective semimodule relative to M; If N is pseudo k-injective semi-module relative to M,A is k-subsemimodule of M,then N is A pseudo k-injective semimodule.
