Real--Dedekind Cut Construction of the Real Line
- PNat The positive integers (very much the same as Nat.thy!)
- PRat The positive rationals
- PReal The positive reals constructed using Dedekind cuts
- RealDef The real numbers
- RealOrd More real numbers theorems- ordering
properties
- RealInt Embedding of the integers in the reals
- RealBin Binary arithmetic for the reals
- Lubs Definition of upper bounds, lubs and so on.
(Useful e.g. in Fleuriot's NSA theory)
- RComplete Proof of completeness of reals in form of the supremum
property. Also proofs that the reals have the Archimedean
property.
- RealAbs The absolute value function defined for the reals
