WebMar 29, 2016 · 1 First you can built a bijection between [a, b] × [c, d] and [0, 1] × [0, 1] thanks to the map (x, y) → (x − a b − a, y − c d − c). Now it remains to find an injection of [0, 1] × [0, 1] into [0, 1]. You can for example use the famous Cantor's bijection. WebBy the CSB Theorem, there is a bijection between A and B.

WebThere are two familiar proofs of the CSB theorem, with somewhat different flavors. One is a kind of back-and-forth argument, attributed to Julius König, involving chains of applications of f f and g g that extend forwards and backwards.
