V Berestovskii, Y Nikonorov - 2020 - Springer
The main purpose of this book is to give an exposition of recent results (obtained with the
essential participation of the authors) on geodesic orbit Riemannian manifolds and their …

[图书][B] Homogeneous Finsler Spaces

S Deng, S Deng - 2012 - Springer
In this chapter we study homogeneous Finsler spaces. In Sect. 4.1, we define the notions of
Minkowski Lie pairs and Minkowski Lie algebras to give an algebraic description of invariant …

Six-dimensional superconformal couplings of non-abelian tensor and hypermultiplets

H Samtleben, E Sezgin, R Wimmer - Journal of High Energy Physics, 2013 - Springer
A bstract We construct six-dimensional superconformal models with non-abelian tensor and
hypermultiplets. They describe the field content of (2, 0) theories, coupled to (1, 0) vector …

Homogeneous Randers spaces with isotropic S-curvature and positive flag curvature

Z Hu, S Deng - Mathematische Zeitschrift, 2012 - Springer
In this paper, we will give a complete classification of homogeneous Randers spaces with
isotropic S-curvature and positive flag curvature. This results in a large class of Finsler …

On left-invariant Einstein Riemannian metrics that are not geodesic orbit

YG Nikonorov - Transformation Groups, 2019 - Springer
In this paper we present the first example of a non-geodesic orbit left-invariant Einstein
metric on a compact Lie group. It should be noted that a suitable metric is defined on the Lie …

On the affine group of a normal homogeneous manifold

S Reggiani - Annals of Global Analysis and Geometry, 2010 - Springer
A very important class of homogeneous Riemannian manifolds are the so-called normal
homogeneous spaces, which have associated a canonical connection. In this study, we …

Associative submanifolds of the Berger space

G Ball, J Madnick - arXiv preprint arXiv:2003.13169, 2020 - arxiv.org
We study associative submanifolds of the Berger space SO (5)/SO (3) endowed with its
homogeneous nearly-parallel G2-structure. We focus on two geometrically interesting …

The skew-torsion holonomy theorem and naturally reductive spaces

C Olmos, S Reggiani - Journal für die reine und angewandte …, 2012 - degruyter.com
We prove a Simons-type holonomy theorem for totally skew 1-forms with values in a Lie
algebra of linear isometries. The only transitive case, for this theorem, is the full orthogonal …

[HTML][HTML] The first eigenvalue of a homogeneous CROSS

RG Bettiol, EA Lauret, P Piccione - The Journal of Geometric Analysis, 2022 - Springer
We provide explicit formulae for the first eigenvalue of the Laplace–Beltrami operator on a
compact rank one symmetric space (CROSS) endowed with any homogeneous metric. As …
