In this paper we investigate computable isomorphisms of Boolean algebras with operators (BAOs). We prove that there are examples of polymodal Boolean algebras with finitely many computable isomorphism ...

The NOT expression is processed first. Then the expressions joined by AND are processed. Finally, the expressions joined by OR are processed. For a complete discussion of the rules for evaluating ...

Tests of characteristics associated with PUIDs are made in a form or mathematical logic known as a Boolean expression (after George Boole who invented it). A Boolean expression combines ...
