A Note on Compactness and Clique Size

David V. Feldman, Alexander Wilce

Say that a topological space has finite, respectively bounded, cliques iff every closed, irreflexive binary relation --- equivalently, every closed, loop-free directed graph --…

Maximal Filters in the Lattice of Partitions of an Infinite Set

David Victor Feldman, Alexander Wilce

We study maximal (proper) filters in the complete lattice of partitions of an infinite set~. In the language of uniform spaces, these are precisely the atoms of the lattice of z…

Order Unit Spaces and Probabilistic Models

John Harding, Alex Wilce

We exhibit a functor from the category OUS of order unit spaces and positive, unit-preserving mappings into the category $\Prob$ of probabilistic models (test spaces with designate…

Classical Explanations in (and of) General Probabilistic Theories

John Harding, Alex Wilce

We introduce a notion of the ``explanation" of one (generalized) probabilistic model by another as particular kind of span in the category $\Prob$ of probabilistic models and morph…

Locally Tomographic Shadows (Extended Abstract)

Howard Barnum, Matthew A. Graydon, Alex Wilce

Given a monoidal probabilistic theory -- a symmetric monoidal category of systems and processes, together with a functor assigning concrete probabilistic…

A Shortcut from Categorical Quantum Theory to Convex Operational Theories

Alexander Wilce

This paper charts a very direct path between the categorical approach to quantum mechanics, due to Abramsky and Coecke, and the older convex-operational approach based on ordered v…
