[PDF][PDF] Double categories, 2-categories, thin structures and connections
R Brown, GH Mosa - Theory Appl. Categ, 1999 - epe.lac-bac.gc.ca
The main result is that two possible structures which may be imposed on an edge symmetric
double category, namely a connection pair and a thin structure, are equivalent. A full proof is …

Pseudo algebras and pseudo double categories
TM Fiore - arXiv preprint math/0608760, 2006 - arxiv.org
As an example of the categorical apparatus of pseudo algebras over 2-theories, we show
that pseudo algebras over the 2-theory of categories can be viewed as pseudo double …

A homotopy 2-groupoid of a Hausdorff space
KA Hardie, KH Kamps, RW Kieboom - Applied Categorical Structures, 2000 - Springer
If X is a Hausdorff space we construct a 2-groupoid G 2 X with the following properties. The
underlying category of G 2 X is thepath groupoid" of X whose objects are the points of X and …

Homotopy invariants of higher dimensional categories and concurrency in computer science
P Gaucher - Mathematical Structures in Computer Science, 2000 - cambridge.org
The strict globular ω-categories formalize the execution paths of a parallel automaton and
the homotopies between them. One associates to such (and any) ω-category [Cscr] three …

Crossed complexes and homotopy groupoids as non commutative tools for higher dimensional local-to-global problems
R Brown - arXiv preprint math/0212274, 2002 - arxiv.org
We outline the main features of the definitions and applications of crossed complexes and
cubical $\omega $-groupoids with connections. These give forms of higher homotopy …
