Summary[edit]
| Description |
English: An illustration of Cantor's diagonal argument for the existence of sets of arbitrary large cardinality (Cantor's theorem). The set T = {n∈ℕ: n∉f(n)} at the bottom cannot occur anywhere in the range of f:ℕ→ℙ(ℕ). The example mapping f is chosen similar to the example enumeration s in File:Diagonal argument 01.pdf. |
