[HTML][HTML] The homotopy theory of type theories

K Kapulkin, PLF Lumsdaine - Advances in Mathematics, 2018 - Elsevier
We construct a left semi-model structure on the category of intensional type theories
(precisely, on CxlCat Id, 1, Σ (, Π ext)). This presents an∞-category of such type theories; we …

Pro-categories in homotopy theory

I Barnea, Y Harpaz, G Horel - Algebraic & Geometric Topology, 2017 - msp.org
Our goal in this paper is to prove an equivalence between the model categorical approach
to pro-categories, as studied by Isaksen, Schlank and the first author, and the∞–categorical …

Internal languages of finitely complete -categories

K Kapulkin, K Szumiło - Selecta Mathematica, 2019 - Springer
We prove that the homotopy theory of Joyal's tribes is equivalent to that of fibration
categories. As a consequence, we deduce a variant of the conjecture asserting that Martin …

[HTML][HTML] Exact completion of path categories and algebraic set theory: Part I: Exact completion of path categories

B van den Berg, I Moerdijk - Journal of Pure and Applied Algebra, 2018 - Elsevier
We introduce the notion of a “category with path objects”, as a slight strengthening of
Kenneth Brown's classical notion of a “category of fibrant objects”. We develop the basic …

Homotopy groups of cubical sets

D Carranza, K Kapulkin - Expositiones Mathematicae, 2023 - Elsevier
We define and study homotopy groups of cubical sets. To this end, we give four definitions of
homotopy groups of a cubical set, prove that they are equivalent, and further that they agree …

Categories of partial equivalence relations as localizations

J Frey - Journal of Pure and Applied Algebra, 2023 - Elsevier
We construct a category of fibrant objects C< P> in the sense of K. Brown from any indexed
frame (a kind of indexed poset generalizing triposes) P, and show that its homotopy category …

Nonexistence of colimits in naive discrete homotopy theory

D Carranza, K Kapulkin, J Kim - Applied Categorical Structures, 2023 - Springer
We show that the quasicategory defined as the localization of the category of (simple)
graphs at the class of A-homotopy equivalences does not admit colimits. In particular, we …
