Is there exist a bijective function from [0,1) to R?
I think it will not possible because [0,1) is not isomorphic R
Any hints/solution will be appreciated
thanks u
Answer
Start with the identity on [0,1). Then send 0 to 1/2, 1/2 to 1/3, etc. In the end you get a bijection from [0,1) to (0,1). To get a bijection, in fact, a homeomorphism from (0,1) to R, you can use eg. tan(πx−π/2).
You cannot get a continuous bijection of [0,1) to R though because then the image of (0,1) has to be an interval. But you get R∖{image of 0}.
