Abstract

In this paper, we study the local ordered \(*\)-vector spaces and their representations. We prove that each Archimedean local ordered \(*\)-vector space, can be represented as a \(*\)-vector subspace of C(X), for some completely Hausdorff compactly generated space X. Furthermore, we show that for every Archimedean local ordered \(*\)-vector space V, there is a representation of V into the \(*\)-algebra of all noncommutative continuous functions on a quantum domain \({\mathcal {E}}\) such that the quantum order induced by this representation is the minimal quantum system structure on V.
