环中的n-核对合元与n-正规元
n-Core Involutory Elements and n-Normal Elements in Rings
摘要
Abstract
By introducing the concepts of n-core involutory elements and n-normal elements in ring R,we gave characterizations for n-core involutory elements and properties of Moore-Penrose invertible n-normal elements.The results show that if a∈ R(#) and m,n ∈ N,then a is an n-core involutory element if and only if (a*)n (a#)n,if and only if (a*)nam =(a(#))nam,if and only if (a*)nam =am (a(#))n,if and only if am (a*)n =(a(#))nam.关键词
