Process algebra with four-valued logic
Jan Aldert Bergstra, Alban Ponse · Journal of Applied Non-Classical Logics · 2000
We propose a combination of a fragment of four-valued logic and process algebra. This fragment is geared to a simple relation with process algebra via the conditional guard construct, and can easily be extended to a truth-functionally complete logic. We present an operational semantics in SOS-style, and a completeness result for ACP with conditionals and four- valued logic. Completeness is preserved under the restriction to some other non-classical logics.
