WitrynaIt is a singular space (the equator is a singularity), but away from the singularities, it has constant negative Gaussian curvature and therefore is locally isometric to a hyperbolic plane. The name "pseudosphere" comes about because it has a two-dimensional surface of constant negative Gaussian curvature, just as a sphere has a surface with ... Witryna11 lis 2024 · Recently, Wang proved that if the metric of a Kenmotsu 3-manifold represents a $*$-Ricci soliton, then the manifold is locally isometric to the hyperbolic space ${\mathbb {H}}^{3}(-1)$. Based on the above facts and discussions in the research of contact geometry, a natuaral question arises. heart of dixie wiki

Witryna9 mar 2024 · If M satisfies the generalized Ricci soliton equation ( 1.4) and X=grad f, f being a smooth function, then f is a constant function. Furthermore, if c_ {2} \ne 0, then the manifold is either locally isometric to the product E^ {n+1} (0)\times S^n (4) for n>1 and flat for n=1 , or the manifold is an Einstein one. Witryna9 lut 2024 · If Φ is both conformal and equiareal, then it is an isometry.

Witryna16 lip 2024 · We infer a small yet explicit and strictly positive lower bound on the Bartnik mass of open sets (non-locally isometric to Euclidean ${\mathbb R}^{3}$) in terms of curvature tensors. Inspired by these results, in the appendix we propose a notion of "sup-Hawking mass" which satisfies some natural properties of a quasi-local mass. Witryna18 paź 2016 · Ok, I'll try a different tact.
