ctl
... A CTL formula is built from three things: 1. Atomic propositions - These are the variables 2. Boolean connectives - AND, OR, NOT, etc. 3. Temporal operators - Express something about paths in the computational tree A temporal operator has two parts: 1. A path quantifier - A (for all paths) or E (the ...

Godel`s Incompleteness Theorem
... will be true iff x is the Gödel number of a FOL sentence, and we can show that if n is the Gödel number of a sentence, then “Sentence(n)” can be derived from PA1-6. In other words, ‘sentence-ness’ is definable (in LA) and representable (in PA). • You can also show that for any recursive set of axiom ...

The Closed World Assumption
... A theory T in predicate logic is a set of sentences. (We do not insist that T contain only definite clauses.) A theory T is said to be complete for ground atomic formulas if, for every ground atomic formula A, either T |= A or T |= ¬A. Let T be any theory (it does not have to be complete for ground ...

If you can successfully do it, you prove p. The logic of the derivation in (6), then, is this. We try to prove ∼P → ...
