#### Abstract

A *lattice ordered ring* (or *l-ring*) *A = A*(*+, *•, v, ʌ) is an abstract algebra closed under four binary operations *+, *•, v, ʌ such that *A*(*+, *•) is a ring, *A*(v, ʌ) is a lattice, and if 0 is the identity element of *A*(+), then

*a, b *≧ 0 imply that *a *+ *b* ≧ 0 and a • b ≧ 0.

As usual, we say that *a* ≧ 0 if *a* v 0 = *a*, and *a* ≧ *b* if (*a* - *b* ) ≧ 0. Moreover, we let |*a*| = *a* v (- *a*).
