Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".
au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.
Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.

Categorical structures enriched in a quantaloid: tensored and cotensored categories. (English) Zbl 1119.18005
Categories enriched in a locally cocomplete bicategory were studied by the reviewer in a 1983 paper reprinted as [R. H. Street, “Enriched categories and cohomology”, Repr. Theory Appl. Categ. 14, 1–18 (2005; Zbl 1085.18010)]. Motivation for that work was R. F. C. Walters’ example of sheaves as enriched categories in which case the base bicategory is locally ordered. A quantaloid is a locally ordered, locally cocomplete bicategory. Categories enriched in a quantaloid exhibit special characteristics, in particular, as the author shows, when it comes to the universal operations of tensoring and cotensoring. Follow up papers will use this work in connection with causal duality and dynamic domains.
