Common use of Relative Algebras over a Concrete Category Clause in Contracts

Relative Algebras over a Concrete Category. We have obtained the third, unified recipe for state-and-effect tri- angles in Theorem 4.8, together with a general healthiness result (Theorem 4.10). The remaining piece towards the full coverage of healthiness results like Theorem 1.1 is: how specific predicate trans- former semantics—specified by a concrete modality (like wp♦ via ♦)—is related to constructs in the general recipe in Theorem 4.8. D To fill this missing piece we shall study a situation where is EM
