👉 In logic and computer science, an "appredicate" is a type of predicate that can be expressed as a Boolean formula. These formulas are used to express logical relations between variables in a given context. Appredications are typically used in formal proof systems like first-order logic or second-order logic, where the goal is to prove statements about variables using these formulas. They allow for the construction of proofs by manipulating the truth values of appredications and their negation.
