Subdirect decomposition of concept lattices
This paper is a continuation of a previous paper of the author where the basic theorem for ''concept lattices'' has been given [Ordered sets, Proc. NATO Adv. Study Inst., Banff/Can. 1981, 445-470 (1982; Zbl 0491.06008)]. A concept lattice can be regarded as a complete meet-sublattice of the power set lattice of ''objects'' determined by the Galois connection given by the ''attributes'' in the obvious way. The purpose of the paper is for some special kind of context to determine the ''scaffolding'' the concept lattice which is a partial join-semilattice. From this result one can determine the concept lattice using an earlier result of the author.
