We confirm a conjecture, about neat embeddings of cylindric algebras, made in 1969 by J. D. Monk, and a later conjecture by Maddux about relation algebras obtained from cylindric algebras. These ...

GEOMETKY.—The grand prize of the mathematical sciences (3000 francs). The problem of finding all the systems of two meromorphic functions in the plane of a complex variable and connected by an ...

The study of computable structures and equivalence relations lies at the intersection of computability theory, algebra and logic, and provides essential insights into the classification and decision ...
