Quantum integrals and anhomomorphic logics

TL;DR

This paper introduces the concept of anhomomorphic logics and quantum integrals over coevents, exploring their properties, filters for reality, and the conditions under which quantum measures generate coevents, with a focus on finite systems.

Contribution

It develops the theory of quantum integrals and anhomomorphic logics, defining 1- and 2-generation of coevents by quantum measures, and analyzes their properties and examples.

Findings

Quantum measures can 2-generate but not 1-generate coevents.

Ordinary measures rarely 1- or 2-generate coevents.

Examples demonstrate differences between 1- and 2-generation.

Abstract

The full anhomomorphic logic of coevents $\ascript ^*$ is introduced. Atoms of $\ascript ^*$ and embeddings of the event set $\ascript$ into $\ascript ^*$ are discussed. The quantum integral over an event $A$ with respect to a coevent $\phi$ is defined and its properties are treated. Integrals with respect to various coevents are computed. Reality filters such as preclusivity and regularity of coevents are considered. A quantum measure $\mu$ that can be represented as a quantum integral with respect to a coevent $\phi$ is said to 1-generate $\phi$. This gives a stronger reality filter that may produce a unique coevent called the ``actual reality'' for a physical system. What we believe to be a more general filter is defined in terms of a double quantum integral and is called 2-generation. It is shown that ordinary measures do not 1 or 2-generate coevents except in a few simple cases. Examples are given which show that there are quantum measures that 2-generate but do not 1-generate coevents. Examples also show that there are coevents that are 2-generated but not 1-generated. For simplicity only finite systems are considered.
