   Format: MarkdownItexWhat you say is not 100% accurate. A 2-framing in the sense of Atiyah is a framing of twice the tangent bundle (lifting the canonical lift to Spin(6)). For isolated 3-manifolds this is the same as a p1-structure, but they differ in families.

   Format: MarkdownItexHi Chris, I was taking notes in Chris Douglas's talk in Erlangen. Maybe I should not have made this $n$Lab note in the first place. I first thought now I give a more extensive discussion, but this feels weird, as I should be citing you guys instead. So to improve on the situation for the moment, what I have done now is this: * I have added to [[2-framing]] the traditional definition; * I have added a pointer to your work (Douglas/Schommer-Pries/Snyder) as far as I can; * I have turned the note into "can be reformulated in terms of $p_1$-structure" with a citation.

   Hi Chris,

   I was taking notes in Chris Douglas’s talk in Erlangen. Maybe I should not have made this $n$Lab note in the first place. I first thought now I give a more extensive discussion, but this feels weird, as I should be citing you guys instead.

   So to improve on the situation for the moment, what I have done now is this:

   • I have added to 2-framing the traditional definition;

   • I have added a pointer to your work (Douglas/Schommer-Pries/Snyder) as far as I can;

   • I have turned the note into “can be reformulated in terms of $p_1$-structure” with a citation.
