摘要
A是数域F上n阶方阵,文中给出用A的最小多项式来表示A的伴随阵的最小多项式的表达式,以及由A的Jordan标准形表示出A之伴随阵的Jordan标准形的方法。
If A is a n×n matrix of a field F,it is argued that the least polynomial of the adjoint matrices of A can be expressed by using the least polynomial of A;and it is also shown that the Jordan canonical form of the adjoint matrices can be expressed by using the Jordan canonical form of A.Methods are given.
