Single-valueness of spinor components
I agree that a global trivialization should not be assumed. But in this particular case, the spin bundle is an $SU(2)$-vector bundle and $\pi_2(SU(2))$ implies the spin bundle is trivial. I think what's wrong in the above is that the region $(\theta \in (0, \pi))$ (where the frame is well defined ) is not a contractible open set. But I am not sure. |

How to prove this Weitzenbock formula?
@HenryT.Horton: (4.14) is for $\Omega^{0,0}(E)$. I managed to prove (4.14), but not the one I am confused about. |

Factor of 2 In the Definition of Metric Contact Structure
I agree with Brendan on the two definitions of $d$: I found at the bottom of page 62, Blair wrote down $d\eta$ formula. I feel that a clear list of convention should be provided at the very beginning of the book. Thanks! |

3d-analog of “every 2d oriented manifold is complex”
Thanks for replying and the algebra is quite interesting. But as you stated it's not an analog I'm looking for. Hope there will be some other suggestions. |
