The paper discusses that orthogonal group O(V, β) over local ring maps orthogonal group O(V, β) over remnant field by homomorphism mapping λ.
研究了局部环R上的正交群On(V,β)以映射λ同态映射到剩余域F上的正交群On(V,β)的性质;映射核λ-K(λ)的作用和性质,以及局部环上正交变换的有关性质和分解。
A type of overgroups of certain subgroups of orthogonal groups are determined over local rings,with the result as follows: Let R be a local ring,M the unique maximal ideal of R,O(2m,R) an orthogonal group over R.
定出了局部环上正交群中一类子群的扩群,得到了如下结果:设R是局部环,M是R的唯一极大理想,O(2m,R)为R上正交群。
The isospectral flows method for solving inverse the eigenvalues problem and its lie group method are studied in this paper,while the corresponding lie group is orthogonal group.
研究了解特征值反问题的等谱流方法及其李群算法,我们取的李群是正交群。
A group orthogonal frequency and code division multiple access scheme were proposed,which was named GOFCDMA.
提出了一种群正交的频分与码分相结合的多址方案——群正交频码分多址,通过在发送端对用户进行分组,每组内采用码分多址,在接收端利用较低复杂度的分组最大似然检测,可以有效提高频谱利用率。
