Which set is the object named by a name τ depends on the generic g, and given g, the model M [g] is the collection of se ...

... Because the encoding string y should end in a long string of 1s, there is at most one such factorisation possible. The Halting Problem is to decide whether a Turing machine halts on a given input. That is, HALTING = {yz : Ty exists and halts on input z}. Note that for any string x, there exists at m ...

... “If pigs could fly then I’d enjoy brussel sprouts!” p : Pigs fly; b : Enjoy sprouts This (p |= b) is an invalid argument. Why use it? The real argument is: p, ¬p |= b which is a valid argument. Why is it valid? There is no counter example where p ∧ ¬p is true and b is false. Ex falso quod libet! i. ...
