摘要
对任意素数p、r>1的整数,A为有限域F_p上的n维可逆矩阵,若A(modp)的周期为T,则A(modp^r)的周期为p^(r-1)T.文中首次提出该定理,并用数学归纳法进行了证明.
For any prime number p, positive integer r, and n-dimensional invertible matrix A on the Galois field Fp, if the least positive period of A(modp) is T, then the least positive period of A(modp^r) is p^r-1T, as is firstly proposed in this paper and proved by means of the mathematical induction.
