研究了某些二阶矩阵及其二阶矩阵对关于弱相似关系的等价分类,讨论了二阶全矩阵代数的kC2-模代数结构和kC3-模代数结构的同构类。在同构意义下给出了二阶全矩阵代数的kS3-模代数结构,且当k为代数闭域时,得到了二阶全矩阵代数的kS3模代数结构的同构分类。
The equivalent classifications of some matrices and pairs of matrices with respect to the weak similarity are studied, respectively. Then by applying these results, the isomorphism classifications of kC2-module algebra structures and kC3module algebra structures on the full matrix algebra M2(k) are described. Finally, kS3module algebra structures on the full matrix algebra M2(k) are given up to isomorphism. When k is an algebraically closed filed, the isomorphism classifications of kS3module algebraic structures on the full matrix algebra M2(k) are obtained.
