N2 - A structure S in a finite signature σ is polynomial-time if the domain of S, and the basic operations and relations of S are polynomial-time computable. Following the approach of semantic programming, for a given polynomial-time structure S, we consider the family B(S) containing all subsets of dom(S), which are definable by a ∆0 formula with parameters. It is known that each of these sets is polynomial-time computable; hence, B(S), endowed with the standard set-theoretic operations, forms a natural Boolean algebra of polynomial-time languages, associated with S. We prove that up to isomorphism, the algebras B(S), where S is a polynomial-time structure, are precisely computable atomic Boolean algebras.
