Abstract:We study the sequent system mentioned in the author's work [18] as CyInFL with 'intuitionistic' sequents. We explore the connection between this system and symmetric constructive logic of Zaslavsky [40] and develop an algebraic semantics for both of them. In contrast to the previous work, we prove the strong completeness theorem for CyInFL with 'intuitionistic' sequents and all of its basic variants, including variants with contraction. We also show how the defined classes of structures are related to cyclic i… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
