Abstract

We consider asymptotically flat manifolds of the form (S3\{P}, G4g), where G is the Green's function of the conformal Laplacian of (S3, g) at a point P. We show if Ric(g) ≥ 2g and the volume of (S3, g) is no less than one half of the volume of the standard unit sphere, then there are no closed minimal surfaces in (S3 \ {P},G 4g). We also give an example of (S3, g) where Ric(g) > 0 but (S3 \ {P}, G4g) does have closed minimal surfaces.
