Algebras of Sets and Combinatorics

The unpublished Russian manuscript Algebry mnozhestv i kombinatorika was translated into English by A. B. Sossinsky. Grinblat, who is not identified, reports his research results, and completes the theory he has been working on in previous publications. All the main results belong entirely to naive set theory. Among his topics are finite sequences of algebras, the general problem, the inverse problem, and semistructures and structures of sets. Annotation c. Book News, Inc., Portland, OR (booknews.com)
