Kirby–Siebenmann class
From Wikipedia, the free encyclopedia
(Redirected from Kirby-Siebenmann invariant)
In mathematics, the Kirby–Siebenmann class is an element of the fourth cohomology group
which must vanish if a topological manifold M is to have a piecewise linear structure. It is named for Robion Kirby and Larry Siebenmann.
