Realizations of some contact metric manifolds as Ricci soliton real hypersurfaces
Jong Taek Cho, Takahiro Hashinaga, Akira Kubo +2
Ricci soliton contact metric manifolds with certain nullity conditions have recently been studied by Ghosh and Sharma. Whereas the gradient case is well-understood, they provided a…
On the moduli spaces of left-invariant pseudo-Riemannian metrics on Lie groups
Akira Kubo, Kensuke Onda, Yuichiro Taketomi +1
In this paper, we formulate a procedure to obtain a generalization of Milnor frames for left-invariant pseudo-Riemannian metrics on a given Lie group. This procedure is an analogue…
Homogeneous Ricci soliton hypersurfaces in the complex hyperbolic spaces
Takahiro Hashinaga, Akira Kubo, Hiroshi Tamaru
A Lie hypersurface in the complex hyperbolic space is an orbit of a cohomogeneity one action without singular orbit. In this paper, we classify Ricci soliton Lie hypersurfaces in t…
A sufficient condition for congruency of orbits of Lie groups and some applications
Akira Kubo, Hiroshi Tamaru
We give a sufficient condition for isometric actions to have the congruency of orbits, that is, all orbits are isometrically congruent to each other. As applications, we give simpl…
