摘要：This note offers a non-deterministic semantics for mbC 1 , introduced by Janusz Ciuciura, and establishes soundness and (strong) completeness results with respect to the Hilbert-style proof system. Moreover, based on the new semantics, we briefly discuss an unexplored variant of mbC 1 which has a contra-classical flavor.
