De Rham invariant
text:
In geometric topology, the de Rham invariant is a mod 2 invariant of a (4k+1)-dimensional manifold, that is, an element of Z / 2 – either 0 or 1. It can be thought of as the simply-connected symmetric L-group L 4 k + 1 , and thus analogous to the other invariants from L-theory: the signature, a 4k-dimensional invariant, and the Kervaire invariant, a (4k+2)-dimensional quadratic invariant L 4 k + 2 . It is named for Swiss mathematician Georges de Rham, and used in surgery theory.
