Two Constructivist Aspects of Category Theory

open access: yesPhilosophia Scientiæ, 2006
Category theory has two unexpected links to constructivism: First, why is topos logic so close to intuitionistic logic? The paper argues that in part the resemblance is superficial, in part it is due to selective attention, and in part topos theory is ...

An Order-Theoretic Quantification of Contextuality

open access: yesInformation, 2014
In this essay, I develop order-theoretic notions of determinism and contextuality on domains and topoi. In the process, I develop a method for quantifying contextuality and show that the order-theoretic sense of contextuality is analogous to the sense ...

Bohrification of local nets [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
Recent results by Spitters et. al. suggest that quantum phase space can usefully be regarded as a ringed topos via a process called Bohrification. They show that quantum kinematics can then be interpreted as classical kinematics, internal to this ringed ...

Towards a Paraconsistent Quantum Set Theory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
In this paper, we will attempt to establish a connection between quantum set theory, as developed by Ozawa, Takeuti and Titani, and topos quantum theory, as developed by Isham, Butterfield and Döring, amongst others.

Steering the Shape‐shifting of Bullvalene‐PdII Complexes Through Steric and Geometric Strain

open access: yesAngewandte Chemie, EarlyView.
This study explores the use of bis‐pyridyl substituted bullvalenes as dynamic shape‐shifting ligands within cis‐capped PdII complexes. The ring position of the pyridyl nitrogen is critical, leading to a range of Pd2L2 metallacycles and simple PdL complexes, each with distinctive bullvalene isomer preferences (represented in the figure by A‐D isomer ...

Is Quantum Field Theory Necessarily “Quantum”?

open access: yesQuantum Reports
The mathematical universe of the quantum topos, which is formulated on the basis of classical Boolean snapshots, delivers a neo-realist description of quantum mechanics that preserves realism.

Ennobling Love and Erotic Elevation: A Response to Six Readings of Ars Erotica

open access: yesEidos. A Journal for Philosophy of Culture, 2022
Preview: In various guises and cultures, the theme of elevating, ennobling love is a recurrent topos in the premodern erotic theory my book traces.

On the validity of the definition of a complement-classifier

open access: yesZagadnienia Filozoficzne w Nauce, 2020
It is well-established that topos theory is inherently connected with intuitionistic logic. In recent times several works appeared concerning so-called complement-toposes (co-toposes), which are allegedly connected to the dual to intuitionistic logic. In

The Topos of Virtuality

open access: yestripleC: Communication, Capitalism & Critique, 2009
Generalizing the conceptual approach to a theory of biosemiotics which is primarily based on insight from mathematical topology , we discuss here the relevance of the cognitive representation of the category of space in terms of the consequences implied ...
