A Boolean algebra B can be
imbedded in a complete Boolean algebra C in such a way that all homomorphisms of
B into complete Boolean algebras can be extended to complete homomorphisms on C
if and only if B is superatomic, that is, every homomorphic image of B is atomic.
This paper is a study of the structure of superatomic Boolean algebras,
through the development of techniques of construction and classification, and
through the representation of these algebras as compact Hausdorff clairsemé
spaces.
