| Derivability: this is about the question which statements can be obtained according to the rules of a calculus. In logic, derivability refers to the ability to prove a statement from a set of premises using the rules of inference of a given logical system. A statement is said to be derivable if there is a proof of it in the system._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
