Transistors wired in series and parallel patterns make up "gates," which accept binary input (0 = no pulse; 1 = pulse) and generate binary output. Although AND requires both inputs to be 1 in order to ...

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 ...

Studia Logica: An International Journal for Symbolic Logic, Vol. 49, No. 2 (1990), pp. 197-214 (18 pages) We illustrate, with three examples, the interaction between boolean and modal connectives by ...
