摘要
证明了交换环上幂等矩阵的伴随矩阵是幂等的 ,同时证明了整环上幂零矩阵的伴随矩阵仍是幂零的 .所得结果推广了复数域上相应的结果 .
In this paper, it is proved that the adjoint matrix of an idempotent matrix over a commutative ring is idempotent and the adjoint matrix of a nilpotent matrix over a domain is also nilpotent. The results generalize the correspondence results over complex field.
