... (ii) For any subset x of A, let [x]R = {y : &x, y' ∈ R}, where R is as given in (i). Let C = {[x]R : x ∈ PA}. If A has exactly three members, how many members does C have? Give your reasons. ...

A Logic of Explicit Knowledge - Lehman College
... Now we drop the operator K from the language, and introduce a family of explicit reasons instead— I’ll use t as a typical one. Following [1, 2] I’ll write t:X to indicate that t applies to X—read it as “X is known for reason t.” Formally, if t is a reason and X is a formula, t:X is a formula. Of cou ...

... The Grand Hotel (example due to David Hilbert) has countably infinite number of rooms, each occupied by a guest. We can always accommodate a new guest at this hotel. How is this possible? Explanation: Because the rooms of Grand Hotel are countable, we can list them as Room 1, Room 2, Room 3, and so ...

Fuzzy logic and probability Institute of Computer Science (ICS
... In our opinion any serious discussion on the relation between fuzzy logic and probability must start by mak ing clear the basic differences. Admitting some simpli fication, we cotL'>ider that fuzzy logic is a logic of vague, imprecise notions and propositions, propositions that may be more or less ...

... the dummy of (∀x)P . We abbreviate (∀x)P by (x)P (as does Church [2]). An occurrence of individual variable x is bound in formula P iff the occurrence is within a subformula of P of the form (x)Q ; otherwise, the occurrence of x is free in P . Precedence conventions allow the elimination of some pare ...
