On the Structure of Sub-Riemannian Geodesic Orbit Manifolds
Huihui An, Zaili Yan, Hui Zhang +1
We study homogeneous sub-Riemannian manifolds whose normal extremals are orbits of one-parameter subgroups of the acting group. Our first main result shows that every sub-Riemannia…

Invariant Einstein metrics on basic classical Lie supergroups
Huihui An, Zaili Yan, Shaoxiang Zhang
This paper presents a systematic study of invariant Einstein metrics on basic classical Lie supergroups, whose Lie superalgebras belong to the Kac's classification of finite dimens…
