Csb theorem
There are many different proofs of this theorem. We present here a direct proof by using the definitions of injective and surjective function. Let be sets and let and be injective functions. We need to show that there is a bijective function We will denote the range of the function by and the range of the function by By … See more We have already found a bijective function between the sets and in Example on the Cardinality of a Setpage. Now we solve the problem by using the Cantor-Schröder-Bernstein theorem. The function is an injection Also, the … See more Notice that the cardinality of is the same as the cardinality of the open unit interval because there exists a bijective function between the sets: … See more Consider the open unit square and the open unit interval To build an injection from to we represent the coordinates of an arbitrary point of the … See more We can map using the function This mapping is bijective. Similarly, the mapping is given by the function that is also bijective.
