Quotient Rings of a Class of Lattice-Ordered-Rings

Extract
An f-ring R with zero right annihilator is called a qf-ring if its Utumi maximal left quotient ring Q = Q(R) can be made into and f-ring extension of R. F. W. Anderson [2, Theorem 3.1] has characterized unital qf-rings with the following conditions: For each q ∈ Q and for each pair d1, d2 ∈ R+ such that diq ∈ R
(i) (d1q)+ Λ (d2q)- = 0, and
(ii) d1 Λ d2 = 0 implies (d1q)+ Λ d2 = 0.
We remark that this characterization holds even when R does not have an identity element.
