Isometries of almost-Riemannian structures on Lie groups
(2018)
A simple Almost-Riemannian Structure on a Lie group G is defined by a linear vector field (that is an infinitesimal automorphism) and dim(G) - 1 left-invariant ones. It is first proven that two different ARSs are isometric ...
ALMOST-RIEMANNIAN GEOMETRY ON LIE GROUPS
(2016)
A simple almost-Riemannian structure (ARS) on a Lie group G is defined by a linear vector field (that is, an infinitesimal automorphism) and d i m (G) - 1 left-invariant ones. We state results about the singular locus, the ...
Interpolation of geometric structures compatible with a pseudo Riemannian metric
(Springer, 2016-11)
Let (M, g) be a pseudo Riemannian manifold. We consider four geometric structures on M compatible with g: two almost complex and two almost product structures satisfying additionally certain integrability conditions. For ...
Estructuras casi-Kähler estáticas en grupos de Lie
(2021)
Una ecuación especialmente sofisticada para evolucionar variedades casi-Kähler es el flujo de curvatura simpléctico, introducido por Streets-Tian. Los puntos fijos de este flujo, que reciben el nombre de estructuras ...
Gibbs–Markov structures and limit laws for partially hyperbolic attractors with mostly expanding central direction
(Elsevier, 2010-03)
We consider a partially hyperbolic set K on a Riemannian manifold M whose tangent space splits as TKM=Ecu⊕Es, for which the center-unstable direction Ecu expands non-uniformly on some local unstable disk. We show that under ...
