We can use predicate logic (first-order logic) to express all of these. CS 245 Logic and Computation Fall 2019 6 / 37. Would you really use predicate logic? Examples of predicate logic in CS245 so far: 1. Every well-formed formula has an equal number of left and right brackets. 2.

A first order formula can be defined inductively as follows: p(t1, …, tn) is a formula if t1, …, tn are terms and p is a predicate of arity n. A formula of this kind is called atomic; (F ∧ G), (F ∨ G) , (F → G), (F ← G) , (F ↔ G) are formulas if both F and G are formulas; (∀x F), (∃x F) are formulas if x is a variable and F is ...

Some tautologies of predicate logic are analogs of tautologies for propo-sitional logic (Section 14.6), while others are not (Section 14.7). Proofs in predicate logic can be carried out in a manner similar to proofs in propositional logic (Sections 14.8 and 14.9). In Section 14.10 we discuss some of the implications of predicate logic as to our
