CLASSIFICATION THEORY FOR ACCESSIBLE CATEGORIES [PDF]
AbstractWe show that a number of results on abstract elementary classes (AECs) hold in accessible categories with concrete directed colimits. In particular, we prove a generalization of a recent result of Boney on tameness under a large cardinal assumption.

Decomposition theories for abelian categories [PDF]
Both the classical approach to decomposition theories and Fisher’s technique of constructing decomposition theories from radical functions are extended to and exploited in the context of abelian categories. These two different approaches to decomposition theories for abelian categories intertwine in one theorem from which flows ...

Category theory and set theory as theories about complementary types of universals [PDF]
Instead of the half-century old foundational feud between set theory and category theory, this paper argues that they are theories about two different complementary types of universals.

Algebraic Presentations of Type Dependency [PDF]
C-systems were defined by Cartmell as the algebraic structures that correspond exactly to generalised algebraic theories. B-systems were defined by Voevodsky in his quest to formulate and prove an initiality conjecture for type theories.

On the Axiomatic Systems of Steenrod Homology Theory of Compact Spaces [PDF]
On the category of compact metric spaces an exact homology theory was defined and its relation to the Vietoris homology theory was studied by N. Steenrod [S].

String diagrams for Strictification and Coherence [PDF]
Whereas string diagrams for strict monoidal categories are well understood, and have found application in several fields of Computer Science, graphical formalisms for non-strict monoidal categories are far less studied.

Competitiveness results from factors beyond the structural conditions and organizational boundaries, such as interorganizational cooperation. Evidence gathered in Brazilian credit unions suggests there is a social process in the firm for generating ...

The technique of modeling Cyberphysical systems using Coalgebra
Relevance. Presently, we observe a rapid pace of development in information technologies, the implementation of which results in a broad percentage of automation in manufacturing processes.

The foundations of category theory are considered. Following the example of Tarski's reductionism for first order logic, the authors have built a logical system and a set theory which they call NaDSet (NaD from Natural Deduction). Subtle use of controlled self-reference and other subtle technical means allows them to avoid artificial distinction ...

Experience Implementing a Performant Category-Theory Library in Coq [PDF]
We describe our experience implementing a broad category-theory library in Coq. Category theory and computational performance are not usually mentioned in the same breath, but we have needed substantial engineering effort to teach Coq to cope with large ...
