给出左极小Abel环的一些刻画,主要证明了如下结果:1)R为左极小Abel环当且仅当2阶上三角矩阵环T2(R)为左极小Abel环;2)R为强左极小Abel环当且仅当 a∈R, e∈MEl(R),|a∨e|≤3;3)设I为R的约化理想,若R/I为左极小Abel环,则R也为左极小Abel环.
In this paper some characterizations of left min-abel rings are given. Following results are obtained= 1) R is a left min-Abel ring if and only if the 2× 2 upper triangular matrix ring T2 (R)over R is a left min-Abel ring; 2) R is a strongly left min-Abel ring if and only if for each a∈R and e∈MEl(R), where |a V e|≤3; 3) Let I be a reduced ideal of R. If R/I is a left min-Abel ring, then so is R.
