PREFACE
Category
Theory is rapidly coming of age as a Mathematical discipline. In this
process it now ap- pears that a central rolle will be played by the
notion of an enriched category. These categories, with hom-sets in a
closed category,--in particular, in a symmetric monoidal closed
categorie-- semeed initially very complez and difficult to manage
effectively. However, independent work by various expertsYoneda,
Linton, Benabou, Eilenberg-Kelly, Lambek, Bunge, Ulmer, Gray,
Palmquist, and others-- step was the discovery of the proper use of
tensors, cotensors, and Kan extensions for enriched categories (A
discovery made simultaneously and independently by Benabou and by
Kelly with Day). As a result, an efficient presentation of enriched
categories is now possible.
This paper by Dubuc collects all these ideas in a compact
exposition wich makes this efficiency very clearand wich also
serve as a basis for Dubuc's own original contributions. I have,
there- fore, recommended to the editors of the Lecture Notes
series the rapid publication
of this paper, to pro- vide easy acces to this foundation for future
devel-opment.
