The pack covers Natural Deduction proofs in propositional logic (L1), predicate logic (L2) and predicate logic with identity (L=). The vast majority of these ...

In a natural deduction proof, it is permissible to make an arbitrary assumption in a nested proof. NB: We can assume anything we like. We can assume anything we ...

One of the important principles of natural deduction is that each connective should be defined only in terms of inference rules without reference to other.

This tutorial is available in several languages: Spanish1 (and PDF), Esperanto2. (and PDF), Catalan3 (and PDF), and English4 (and PDF). ... natural deduction ...

The differences and similarities among these methods of representing natural deduction proofs are easiest to see in an example of a proof done in the different ...

The task here is to extend natural deduction for sentential logic by adding rules for handling quantifiers and variables. The natural way to do this is to use ...

We are going to introduce a number of derivation rules, which are, in a way, the atomic steps in a derivation. These derivations rules are designed (by Gentzen) ...

Natural deduction systems are meant to closely parallel the informal reason- ing used in mathematical proof (hence it is somewhat “natural”). Natural.

Natural deduction is a family of derivation systems with derivation rules designed to mimic the way people reason deductively. 4 / 27. Page 5. Natural deduction.
