Letbe an arbitrary ring with an identity 1, and suppose thatcontains a pair of elementsu, vsuch thatWe introduce the elementsfori, j= 1, 2, 3, …, where it is understood thatu0= l =v0. It can be verified directly that theeijthus defined satisfy the multiplication table for matrix units:In particular the elementsei=eijare orthogonal idempotent elements. Noeij=0. For by (3) the vanishing of one of theeijimplies the vanishing of all; in particular, it implies thatcontrary to (1).
