    Added to spin structure a quick section Examples – On the 2-sphere computing the unique spin structure on the 2-sphere explicitly as a square root of the canonical bundle. (Still needs polishing…)

    have expanded the Definition-section at spin structure a bit more, highlighting the obstructing 2-bundles / bundle gerbes a bit more.

    added a brief remark on the spin-structure on S nS^n (here)

    This really comes, ultimately, from the coset space realization S n=Spin(n+1)/Spin(n)S^n = Spin(n+1)/Spin(n).

    I was looking for an author who would admit that explicitly. No luck yet, but have to run now.

    made more explicit (here) how the spin-structure on the n-sphere comes from its coset-space realization
