摘要 本文证明了置换环上的正则稳定矩阵是幂等矩阵和可逆矩阵的积,进一步证明了置换环上的正则稳定矩阵可以对角化。 Let R be an exchange ring. It is shown that every square regular stable matrix over R admits a diagonal reduction. For any stable matrices A,B ∈ Mn(R), if AB and BA have Drazin inverse, we also prove that there exists U ∈ GLn(R) such that (AB)^d = U(BA)^dU-1.
