Template:Scalar curvature result
Statement
A closed simply connected manifold of dimension at least 5 satisfies at least one of these two conditions:
- It has a Riemannian metric admitting a spin structure
- It has a Riemannian metric with positive scalar curvature
This is a corollary of the Gromov-Lawson theorem on surgery.
