Line 143: :Congratulations! You found an error that has been in the article since [http://en.wikipedia.org/w/index.php?title=Brouwer_fixed_point_theorem&action=historysubmit&diff=57654312&oldid=46581414 June 2006]! :The idea is valid, though. I will replace the example with a hopefully correct one using the homeomorphism of the interval (-π/2,π/2) with the real line via the tan and arctan functions. Since I have just made this up and did not put much thought into it, it would be nice if you could check it.

Another, maybe simpler example, would be the open interval (0,1) and the function <math> f(x) = \frac{x}{2} </math>. Since the function doesn't have to be bijective, this should also work out. --[[Special:Contributions/84.73.188.172\|84.73.188.172]] ([[User talk:84.73.188.172\|talk]]) 14:28, 22 January 2011 (UTC)
