On the transverse Scalar Curvature of a Compact Sasaki Manifold

Weiyong He (2014)

Complex Manifolds

Similarity:

We show that the standard picture regarding the notion of stability of constant scalar curvature metrics in Kähler geometry described by S.K. Donaldson [10, 11], which involves the geometry of infinitedimensional groups and spaces, can be applied to the constant scalar curvature metrics in Sasaki geometry with only few modification. We prove that the space of Sasaki metrics is an infinite dimensional symmetric space and that the transverse scalar curvature of a Sasaki metric is a moment...

Complete gradient Ricci solitons

Udo Simon (2015)

Colloquium Mathematicae

Similarity:

For complete gradient Ricci solitons we state necessary conditions for a non-trivial soliton structure in terms of intrinsic curvature invariants.
