Answer Sets for Propositional Theories
... a formula is positive if it is in the antecedent of an even number of implications. An occurrence is strictly positive if such number is 0. An occurrence of an atom in a formula is negated if it is in a subformula of the form F ⊃ ⊥. For instance, in a formula (p ⊃ ⊥) ⊃ q, the occurrences of p and q ...

... This implies p = ¢ 6 and p •Inf¢(p<, p>). Properties (2) and (3) immediately follow from the general fact 6 <~ 6' ~ r6, ~_ r6 and the characterizations of the final topologies of p, p< and p>. [] For a given representation 6 of a set M we can ask which informations about x = 6 ( p ) • M are finitely ...

possible-worlds semantics for modal notions conceived as predicates
... We think that the operator approach might have some merits for instance in linguistics and computer science, but it fails at its main application in philosophical logic: it does not provide an illuminating analysis for necessity, knowledge, obligation and so on. For it does not allow for the formali ...

Godel`s Proof
... we are perfectly able to make “fixed sets of directives” that have some of these qualities. To be sure, we have not yet come close to producing a computer program that has anything remotely resembling the flexibility of the human mind, and in this sense Ernest Nagel and James Newman were exactly on th ...

The Cantor Set and the Cantor Function
... Is there anything left? Yes, at least the endpoints of the deleted middle third subintervals. There are countably many such points. Are there any other points left? Yes, in some sense, a whole lot more. But in some other sense, just some dust - which in some ways is scattered, in some other ways it ...

... modeled is that in all the states an agent considers possible at a state s, fewer concepts may be defined than are defined at state s. Because a proposition p may be undefined at a given state s, the underlying logic in HMS is best viewed as a 3-valued logic: a proposition p may be true, false, or ...
