Yamabe Invariants, Homogeneous Spaces, and Rational Complex Surfaces
Claude LeBrun Department of Mathematics, Stony Brook University, Stony Brook, NY 11794-3651, USA
Abstract:
The Yamabe invariant is a diffeomorphism invariant of smooth compact manifolds that arises from the normalized Einstein–Hilbert functional. This article highlights the manner in which one compelling open problem regarding the Yamabe invariant appears to be closely tied to static potentials and the first eigenvalue of the Laplacian.
Keywords:
scalar curvature, conformal structure, Yamabe problem, diffeomorphism invariant.
