Obstructions to the existence of a flat connection on a vector bundle
A $d$-dimensional flat real vector bundle $E→M$ is classified by a map $\def\B{{\sf B}}\def\GL{{\rm GL}}M→\B\GL(d)_δ$, where $\GL(d)_δ$ is the orthogonal group equipped with the discrete topology.

Reference for $E_{\infty}$-ness of the Chern Character
The answer really depends on one's desired choice of definitions for KU, HQ, and the Chern character itself;
some definitions allow one to produce a very short definition of the Chern character as an …

what is a spinor structure?
A spin structure on a real vector space V equipped with a real quadratic form μ
is an invertible bimodule (i.e., a Morita equivalence)
from Cl(V,μ) to Cl(Rdim(V),ν).
Here ν is the direct sum of dim(V) …

1d TQFT minus connection =?
Going into more detail (and consequently making more and more mistakes), a vector bundle with connection allows to assign to a point the fibre over that point, and to a path the monodromy (or holon …
