Higher spins and Finsler geometry

Journal of High Energy Physics
Finsler geometry is a natural generalization of (pseudo-)Riemannian geometry, where the line element is not the square root of a quadratic form but a more general homogeneous function. Parameterizing this in terms of symmetric tensors suggests a possible

On submanifolds of pseudo-hyperbolic space with 1-type pseudo-hyperbolic gauss map

, 2016
In this paper, we examine pseudo-Riemannian submanifolds of a pseudo-hyperbolic space ?m-1 s (-1) ? Em s+1 with finite type pseudo-hyperbolic Gauss map.

Essential Conformal Fields in Pseudo-Riemannian Geometry. II

, 1997
We study conformal vector fields on pseudo- Riemannian manifolds. In the case of conformally flat manifolds, the main tool is the conformal development map into the projective quadric.

HYPERBOLIC SETS FOR THE FLOWS ON PSEUDO-RIEMANNIAN MANIFOLDS

, 2018
In this paper we introduce and consider the hyperbolic sets for the flows on pseudo-Riemannian manifolds. If $\Lambda $ is a hyperbolic set for a flow $\Phi $, then we show that at each point of $\Lambda $ we have a unique decomposition for tangent space

Conformal deformations of the Riemannian metrics and homogeneous Riemannian spaces [PDF]

, 2002
summary:In this paper we investigate one-dimensional sectional curvatures of Riemannian manifolds, conformal deformations of the Riemannian metrics and the structure of locally conformally homogeneous Riemannian manifolds. We prove that the nonnegativity

PMCV hypersurfaces in non-flat pseudo-Riemannian space forms

In this paper, we prove that PMCV (i.e. \Delta\vec{H} is proportional to \vec{H}) hypersurface M^n_r of a non-flat pseudo-Riemannian space form N^{n+1}_s(c) with at most two distinct principal curvatures is minimal or locally isoparametric, and compute ...
