WebSep 24, 2024 · As described above, we want to send even integers to the first set, and odd integers to the second set. We can do this via the following bijective map g: Z → S defined by g ( n) = { 3 n 2 + 1 if n is even, and 3 n − 1 2 + 2 if n is odd. We then get the desired one-to-one correspondence by composing the two functions. That is, the function WebThe set of rational numbers is countable. The most common proof is based on Cantor's enumeration of a countable collection of countable sets. I found an illuminating proof in [ Schroeder, p. 164] with a reference to [ Sagher ].
