Feb 1, 2012 at 5:38	comment	added	Benoît Kloeckner		@Junyan Xu: you're half right, in fact if you want surfaces from tubular neighborhoods, you need to restrict to $\mathbb{R}^3$. Now corrected, thanks for noticing.

Jan 31, 2012 at 15:09	comment	added	Junyan Xu		I think for $n=1$ you get a cylinder only when you embed the graph into $\mathbb{R}^3$ instead of $\mathbb{R}^n=\mathbb{R}$. Also, $S^2$ and $S^3$ should lie in $\mathbb{R}^n$.
