Compressions on Partially Ordered Abelian Groups
If A is a C*-algebra and p ∈ A is a self-adjoint idempotent, the mapping a 7→ pap is called a compression on A. We introduce effect-ordered rings as generalizations of unital C*-algebras and characterize compressions on these rings. The resulting characterization leads to a generalization of the notion of compression on partially ordered abelian groups with order units.
متن کاملLogic and Partially Ordered Abelian Groups
The unit interval in a partially ordered abelian group with order unit forms an interval effect algebra (IEA) and can be regarded as an algebraic model for the semantics of a formal deductive logic. There is a categorical equivalence between the category of IEA’s and the category of unigroups. In this article, we study the IEA-unigroup connection, focusing on the cases in which the IEA is a Boo...
متن کاملFinitely presented partially ordered abelian groups
We study the partially-ordered abelian group, F (P; R), generated by a set of generators,P , and inequality relations, R, and its representations in Euclidean space. First F (P; R) is deened by a universal property and then existence is shown proof-theoretically. We then characterize the order structure of F (P; R). The rst main result of the paper utilizes the Marriage Theorem to prove that if...
متن کاملOn component extensions locally compact abelian groups
Let $pounds$ be the category of locally compact abelian groups and $A,Cin pounds$. In this paper, we define component extensions of $A$ by $C$ and show that the set of all component extensions of $A$ by $C$ forms a subgroup of $Ext(C,A)$ whenever $A$ is a connected group. We establish conditions under which the component extensions split and determine LCA groups which are component projective. ...
متن کاملCombinable Extensions of Abelian Groups
The design of decision procedures for combinations of theories sharing some arithmetic fragment is a challenging problem in verification. One possible solution is to apply a combination method à la Nelson-Oppen, like the one developed by Ghilardi for unions of non-disjoint theories. We show how to apply this non-disjoint combination method with the theory of abelian groups as shared theory. We ...
