Univalent categories of modules
JGT Flaten - Mathematical Structures in Computer Science, 2023 - cambridge.org
We show that categories of modules over a ring in homotopy type theory (HoTT) satisfy the
internal versions of the AB axioms from homological algebra. The main subtlety lies in …

Homotopy limits and colimits and enriched homotopy theory
M Shulman - arXiv preprint math/0610194, 2006 - arxiv.org
Homotopy limits and colimits are homotopical replacements for the usual limits and colimits
of category theory, which can be approached either using classical explicit constructions or …

Enriched weakness
S Lack, J Rosický - Journal of Pure and Applied Algebra, 2012 - Elsevier
The basic notions of category theory, such as limit, adjunction, and orthogonality, all involve
assertions of the existence and uniqueness of certain arrows. Weak notions arise when one …

[PDF][PDF] A note on unenriched homotopy coends
SB ISAACSON - 2009 - Citeseer
Homotopy coends are an example of an indexed homotopy colimit. In this expository note,
