... makes intuitionistic analysis expressible in the same language as a portion of classical analysis, as Kleene observed. But also, according to which mathematical axioms are present, the sequence variables can be interpreted as ranging over constructive functions (determined by algorithms) instead of ...

... This gives H a = H. It now only remains to show that (b)⇔(c). But this is easy a−1 Ha = H ⇔ a · a−1 Ha = aH ⇔ Ha = aH. This finishes the proof. 2 Definition. Let G be a group with a subgroup H. The number of left cosets of H in G is called the index of H in G and is denoted [G : H]. Remark. Suppose ...

Proposition: A proposition or statement is a declarative sentence which is either true or false but not both. The truth or falsity of a proposition is called its truth-value.

... Kemp gave a proof that was deemed false 11 years after it was published! His proof, however, contains the essential ideas that were used in subsequent proofs. In our case, we will not learn much from a false proof now, but it will give some insight about the nature of what a proof really is. Conside ...
