Lattice ordered ring
WebYang proved that a lattice-ordered ring R is a totally ordered skew-field if and only if every strictly positive element of R is invertible and each square in R is positive. In this note, we construct a simple example to explain the difference between order-isomorphisms and lattice-isomorphisms, and show that the difference can be dropped in lattice-ordered … Web1 sep. 1981 · JOURNAL OF ALGEBRA 72, 223-236 (1981) Examples of Lattice-Ordered Rings STUART A.

Hibi rings. Let L be a finite lattice and S = K[xa a ∈ L] a polynomial ring over a field K. The Hibi ring of L, denoted K[L], is the quotient ring S/I where I is the ideal generated by all binomials xaxb −xa∧bxa∨b for a,b ∈ L. These rings were introduced by Hibi in [12], where he proves that K[L] is toric if and only if
WebPartially ordered rings have been considered by several authors. Especially, the systematic foundation of lattice-ordered rings has been given by Birkho¤ and Pierce [2]. Recently, an interesting result of a lattice-ordered skew field has been obtained in [10]. In this paper, we assume that all rings are non-zero commutative rings with identity. Web20 nov. 2024 · 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 d 1, d 2 ∈ R + such that d i q ∈ R

In abstract algebra, a partially ordered ring is a ring (A, +, ·), together with a compatible partial order, that is, a partial order on the underlying set A that is compatible with the ring operations in the sense that it satisfies: An ordered ring, also called a totally ordered ring, is a partially ordered ring where is additionally a total order.

It consists of a partially ordered set in which every pair of elements has a unique supremum (also called a least upper bound or join) and a unique infimum (also called a greatest lower bound or meet). An example is given by the power set of a set, partially ordered by inclusion, for which the supremum is the union and the infimum is the intersection.
