\hproblem Show that if $p,q$ are elements of the interior of the closed unit ball 
\def\Ball{\mathbb{B}}
$$
\Ball^n=\{x\in\Reals^n: \abs{x}\le 1\},
$$ 
then there is a homeomorphism $\phi:\Ball^n\ra\Ball^n$
such that $\phi(p)=q$ and such that $\phi(x)=x$ for every $x$ with
$\abs{x}=1$.  This problem is a little tricky; be
as rigorous as you can be without sweating the details.
Munkres Theorem 26.6 will be handy.
