Curvature properties of Lie hypersurfaces in the complex hyperbolic space
Tatsuyoshi Hamada, Yuji Hoshikawa, Hiroshi Tamaru
A Lie hypersurface in the complex hyperbolic space is a homogeneous real hypersurface without focal submanifolds. The set of all Lie hypersurfaces in the complex hyperbolic space i…
Parabolic subgroups of semisimple Lie groups and Einstein solvmanifolds
Hiroshi Tamaru
In this paper, we study the solvmanifolds constructed from any parabolic subalgebras of any semisimple Lie algebras. These solvmanifolds are naturally homogeneous submanifolds of s…
Noncompact homogeneous Einstein manifolds attached to graded Lie algebras
Hiroshi Tamaru
In this paper, we study the nilradicals of parabolic subalgebras of semisimple Lie algebras and the natural one-dimensional solvable extensions of them. We investigate the structur…
Lie groups locally isomorphic to generalized Heisenberg groups
Hiroshi Tamaru, Hisashi Yoshida
We classify connected Lie groups which are locally isomorphic to generalized Heisenberg groups. For a given generalized Heisenberg group , there is a one-to-one correspondence b…
Cohomogeneity one actions on noncompact symmetric spaces of rank one
Jurgen Berndt, Hiroshi Tamaru
We classify, up to orbit equivalence, all cohomogeneity one actions on the hyperbolic planes over the complex, quaternionic and Cayley numbers, and on the complex hyperbolic spaces…
