w-核EP逆在对合环上的新刻画
New Characterization of w-Core EP Inverse in Involutive Rings
摘要
Abstract
We considered the w-core EP inverse in involutive rings and discussed its properties from two aspects.On the one hand,the w-core EP decomposition was defined,and a new characterization of the w-core EP inverse was given through the w-core EP decomposition,and some new properties of the w-core EP invertible element were discussed.On the other hand,e=aⒹw(aw)k+1,f=waⒹw(aw)ka and the projection element p=awaⒹw were introduced.The w-core EP core inverse was equivalently characterized by using e,f and the projection element p,and the w-core EP orderaⒹ≤wb was defined accordingly.The properties and its equivalent characterizations of the w-core EP order were studied.关键词
