Similarly p0(x)T= p0(T"(x)). Thus p0(A) is an ideal in M(A). In the future, we shall frequently identify A with p0(A). In this case we will write T'(x) as Tx and T"(x) as xT. The defining equation for a double centralizer will then appear as the associative law for multiplying elements of A and M(A).
