Abstract:
We prove that a topological manifold $M$ of dimension $n$ is $(n - 2)$-connected if each Cantor set in $M$ is contained in an open $n$-ball of $M$. An immediate consequence is that a compact manifold $N$ of dimension $n(n \geq 5)$ is homeomorphic to the $n$-sphere if and only if every Cantor set of $N$ is contained in an open $n$-ball of $N$. This consequence generalizes a $3$-dimensional theorem of Doyle and Hocking.References
