在COHN研究三维埃尔米Z[i]模及其基的特性的基础上,用数论的方法突破数与矩阵具有不同性质的障碍,研究高维埃尔米Z[i]模的性质,给出四维埃尔米Z[i]模的基的一种刻画,推广有关低维Z[i]模的相关结果.
Based on a 3-dimensional Hermitian module over Z[i] researched by COHN, and the properities of the module, difficulties made by the different properties between the number and the matrix are solved in terms of the number theory. The properities of a 4-dimensional Hermitian module over Z [i] are researched and one of its bases is described, i.e. COHN' s result is generalized.
