# Continuous bijection from open n- ball to closed n- ball

Does there exist a continuous bijection from open n ball to closed n-ball? One with a simple argument can show that no such function exists for n=1.But, what about n>1?

For those who arrive later, the case $n=1$ is discussed here. – lhf May 31 '11 at 12:50

Is there a simpler proof for the special case in the question? In particular, for $n=2$? – lhf May 31 '11 at 13:04
Not that I can see as yet. You only need the original Jordan curve theorem, rather than the $n$-dimensional generalization, but that's not much gain. – Chris Eagle May 31 '11 at 13:12
