摘要
通过分析域k上n元多项式代数在其不变子环上基的性质,并对n阶对称群做相应的划分,得到四元多项式代数的判别式.
By analyzing the properties of the basis of k-polynomial algebragenerated by n elements over their invariant subring,and dividing the symmetric group with n letters,we obtained the discriminant of polynomial algebragenerated by four elements.
