Metrics of Pinched Curvature on Heintze Spaces of Carnot-type
@article{Healy2020MetricsOP, title={Metrics of Pinched Curvature on Heintze Spaces of Carnot-type}, author={Brendan Burns Healy}, journal={arXiv: Differential Geometry}, year={2020} }
Rank-one symmetric spaces have a generalization to a larger class of Lie groups that are one-dimensional extensions of nilpotent groups. By examining some metric properties of these symmetric spaces, we motivate and prove the existence of analogous metrics on Heintze spaces of Carnot-type. As an application of this construction, we see that Heintze spaces with H-metrics are of Iwasawa type, fail to have the Einstein condition, and admit a useful symmetric adjoint action. We also introduce the…

We consider the 2-stein condition on k-step Carnot spaces S. These spaces are a subclass in the class of solvable Lie groups of Iwasawa type of algebraic rank one and contain the homogeneous Einstein…

Carnot groups are distinguished spaces that are rich of structure: they are those Lie groups equipped with a path distance that is invariant by left-translations of the group and admit automorphisms…

Abstract.Let M be a complete Riemannian metric of sectional curvature within [−a2,−1] whose fundamental group contains a k-step nilpotent subgroup of finite index. We prove that a ≥ k answering a…
Three-step Harmonic Solvmanifolds
