Goguen Categories
Michael Winter
This paper is a survey of the theory of Goguen categories which
establishes a suitable categorical description of L-fuzzy relations,
i.e., of relations taking values from an arbitrary complete Brouwerian
lattice L instead of the unit interval [0,1] of the real numbers. In
particular, we concentrate on representability, the existence of crisp
versions of several categorical constructions, and operations derived
from suitable binary functions on the underlying lattice of scalar
elements, i.e., on the abstract counterpart of L.
