 May28 comment Hausdorff Dimension and Hausdorff measureThanks Leonid. I still confused on how to calculate the Hausdorff measure of the general cantor set, since it needs to take infimum over all coverings with diameter $\epsilon$ and then let it goes to zero. Why covered by the intervals is enough? May28 asked Hausdorff Dimension and Hausdorff measure Apr14 asked Given Poincare Polynomial find the manifold. Apr13 comment Orientation on $\mathbb{CP}^2$Thanks, that's really help. Apr13 accepted Orientation on $\mathbb{CP}^2$ Apr13 awarded Commentator Apr13 comment Orientation on $\mathbb{CP}^2$So the idendity map between $\mathbb{CP}^2$ and $\overline{\mathbb{CP}}^2$ can not be considered as a homeomorphism between these two 'oriented' manifolds. Correct? Apr13 comment Orientation on $\mathbb{CP}^2$But there is no orientation reversing map from $\mathbb{CP}^2$ to itself. which implies the above two are not homeomorphic! I am crazy.... There must be some stupid mistake I made in my argument, but i can't find it. Apr13 comment Orientation on $\mathbb{CP}^2$Thanks, But whether $\mathbb{CP}^2$ and $\overline{\mathbb{CP}}^2$ homeomorphic to each other?

Nov15 comment Proof of Bochner formula/ Weitzenböck formula in a non-normal frameThe term $\nabla f \langle \nabla_{e_{\alpha}}\nabla f, e_{\alpha}\rangle$ means the vector $\nabla f$ acts on the function $\langle \nabla_{e_{\alpha}}\nabla f, e_{\alpha} \rangle$ thing, so it's a scalar.
