In the first paper of this series, the notion of a manual of operations and its (generalized) sample space was introduced. For each such manual of operations, a so-called logic was constructed. In the present paper, some of the algebraic properties of such logics are identified with the corresponding operational properties of the manual.
The recent study of operational statistics (see [2; 4; 5; 10 ; 11 ; 12 ; 13 ; 14 ; 15 ; 16]) describes a generalized sample space which represents the set of all possible outcomes of a collection of coherently related operations (experiments). This approach to probability generalizes the classical notion of a sample space due to A. N. Kolmogorov [8], and it gives the concept somewhat wider applicability. For instance in [4] and [14], D. J. Foulis and C. H. Randall set out the start of a program wherein a generalized sample space (hereafter called a GSS) and its affiliated partially ordered set of generalized propositions could be a framework within which a genuinely operational interpretation of the so called “logic” of quantum mechanical systems may be found.
This paper develops some of the work of Foulis, Randall, Aerts, and Piron in the fields of empirical science and quantum logic from an algebraic point of view. More specifically, it begins with three axioms of what is called a 'subtraction algebra,' and generates various theorems associated with properties which are useful in empirical science. After a foundation is established, it moves on to define the term manual. This term is defined as a dominated, atomic, semi-Boolean algebra which satisfies an additional condition called condition M. Several properties of the manual are discussed, and different types of manuals are given: classical semi-classical and non-classical. The paper defines operational complements, operational perspectively, atoms, events, and tests, before moving on to define a logic, and how it is derived from a manual. Properties of the logic are discussed, including a subtraction operation, a partial order, and an ortho complement. Next, a computer program is presented. Its purpose is to take a finite semi-Boolean algebra and decide if the algebra is a manual. This is followed by a brief non-classical probabilistic discussion, which includes topics such as weights, pure states, and dispersion-free states. Aerts' and Piron's work with properties, states, and questions is briefly discussed before moving on to several examples, some of them arising from navigation problems. The examples include the hook, the square, the Wright Triangle, and the free algebra. Empirical techniques are demonstrated on these examples. The examples comprise the bulk of this paper.
A manual of operations is a model for a collection of physical experiments, or a collection of (perhaps overlapping) sample spaces. To understand this theory, it is essential to understand the relations between manuals. Hence, in this dissertation, we study the morphisms (and, more specifically, the interpretations) of manuals. This is followed by an investigation of the categorical properties of the tensor product of two manuals. We define biinterpretations and prove a universal mapping theorem. We then prove that the tensor product is associative, and define, using an inductive limit, an infinite tensor product. In the final chapter, we develop a language and theory that is broad enough to encompass much of the work which has been done under the general title of "quantum logic."
