p1-structure

Idea

c-structure for cc the 1st Pontryagin class p 1p_1, o.e. trivialization of p 1p_1.

In the presence of Spin structure then p 1p_1-structure is also called string structure. In the presence of (just) orientation (i.e. w1-structure?) on 3-manifolds then p 1p_1-structure is closely related to Atiyah 2-framing structure.
