Computably enumerable boolean algebras

Other Titles
Abstract
We study computably enumerable boolean algebras, focusing on Stone duality and universality phenomena. We show how classical Stone duality specializes to c.e. boolean algebras, giving a natural bijection between c.e. boolean algebras and $\Pi^0_1$ classes. We also give a new characterization of computably universal-homogeneous c.e. boolean algebras, which yields a more direct proof of the computable isomorphism between the Lindenbaum algebras of theories which satisfy the hypotheses of the second incompleteness theorem.
