... predicate P r as the necessity operator in some suitable modal logic, and much work on modal fixed points was done in the seventies by C. Bernardi, D. de Jongh and G. Sambin. It was proven independently by the three that modal fixed points are unique, and de Jongh and Sambin also presented proofs ...

Section 1.2-1.3
... In a proof of a statement (8n b) P (n) by mathematical induction, b is referred to as the base value. The proof of P (b) is called the base step and the proof of (8n b) [P (n) ! P (n + 1)] is called the inductive step. In the latter proof diagram of proof strategy 1.3.1, the assumption P (n) is call ...

... Now consider 4 photos. There would be 5 · 4! = 5! possible arrangements. Extrapolating to 30 photos, we would get 31 · 30! = 31! possible arrangements. b) In how many ways can I post these photos to the web pages if the order in which the photos appear on those pages does not matter? In the case whe ...
