FITTING环的结构
摘要
本文给出了具有下列条件的结合环R的结构:R上任-n阶方阵A
有A=Q[U N]Q-1(Q
U是可逆矩阵
N是幂零矩阵)。
Abstract
Let R be a ring with 1
Rn×n denotes the ring of n×n matrices over R. If every A∈Rn×n implies that A=Q[|U N|]Q-1 for some invertible matrices Q
U and some nilpotent matrix N. Then R is called Fitting ring.The purpose of the note is to discuss basic properties of Fitting ring and to solve on open question which is given in paper [1].
