A Finitely Axiomatized Non-Classical First-Order Theory Incorporating Category Theory and Axiomatic Set Theory

open access: yesAxioms, 2021
It is well known that Zermelo-Fraenkel Set Theory (ZF), despite its usefulness as a foundational theory for mathematics, has two unwanted features: it cannot be written down explicitly due to its infinitely many axioms, and it has a countable model due ...

The Axiomatic Approach to Non-Classical Model Theory

open access: yesMathematics, 2022
Institution theory represents the fully axiomatic approach to model theory in which all components of logical systems are treated fully abstractly by reliance on category theory. Here, we survey some developments over the last decade or so concerning the

Type theories in category theory

open access: yesCoRR, 2021
We introduce basic notions in category theory to type theorists, including comprehension categories, categories with attributes, contextual categories, type categories, and categories with families along with additional discussions that are not very closely related to type theories by listing definitions, lemmata (with detailed, diagram-rich proofs ...

Conflict Resolution in Mechatronic Collaborative Design Using Category Theory

open access: yesApplied Sciences, 2021
Due to the multitude of disciplines involved in mechatronic design, heterogeneous languages and expert models are used to describe the system from different domain-specific views. Despite their heterogeneity, these models are highly interrelated.

Rewriting techniques for relative coherence [PDF]

open access: yesLogical Methods in Computer Science
A series of works has established rewriting as an essential tool in order to prove coherence properties of algebraic structures, such as MacLane's coherence theorem for monoidal categories, based on the observation that, under reasonable assumptions ...

Pretorsion theories [PDF]

open access: yes, 2021
Pretorsion theories∗ The notion of pretorsion theory is a wide extension of the classical notion of torsion theory in an abelian category. The idea is to associate, with any pair (T, F) of full replete subcategories of a category C, a corresponding ...

Theoretical Basis of the Ideological and Political Education Category: Based on Studying the Marxist Category Theory [PDF]

open access: yes, 2014
In the scientific and rigorous system of Marxist theory, category is the basic logic unit. The great strength of Marxist category theory finds its full expression in the science and vitality of Marxist theory.

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 ...
