Abstract

This paper constructs a cirquent calculus system and proves its soundness and completeness with respect to the semantics of computability logic. The logical vocabulary of the system consists of negation $${\neg}$$ , parallel conjunction $${\wedge}$$ , parallel disjunction $${\vee}$$ , branching recurrence 驴, and branching corecurrence 驴. The article is published in two parts, with (the present) Part I containing preliminaries and a soundness proof, and (the forthcoming) Part II containing a completeness proof.
