• A classical-quantum imperative language with an operational and denotational semantics. Two Hoare-style proof systems that are satisfaction-based. An abstract system is sound relatively complete, a concrete sound. We investigate the formal semantics of simple has both classical quantum constructs. More specifically, we provide semantics, two systems: one one. The satisfaction-based, as inspir...

For programming languages whose denotational semantics uses xed points of domain constructors of mixed variance proofs of correspondence between operational and denotational semantics or be tween two di erent denotational semantics often depend upon the exis tence of relations speci ed as the xed point of non monotonic operators This paper describes a new approach to constructing such relations...
