Diastatic entropy and rigidity of complex hyperbolic manifolds
Let f : Y → X be a continuous map between a compact real analytic Kähler manifold (Y, g) and a compact complex hyperbolic manifold (X, g0). In this paper we give a lower bound of the diastatic entropy of (Y, g) in terms of the diastatic entropy of (X, g0)

Lagrangian systems on hyperbolic manifolds [PDF]
This paper gives two results that show that the dynamics of a time-periodic Lagrangian system on a hyperbolic manifold are at least as complicated as the geodesic flow of a hyperbolic metric. Given a hyperbolic geodesic in the Poincaré ball, Theorem A asserts that there are minimizers of the lift of the Lagrangian system that are a bounded distance ...

Asymptotic measure-expansiveness for generic diffeomorphisms
In this paper, we will assume MM to be a compact smooth manifold and f:M→Mf:M\to M to be a diffeomorphism. We herein demonstrate that a C1{C}^{1} generic diffeomorphism ff is Axiom A and has no cycles if ff is asymptotic measure expansive.

Hyperbolic Gradient-Bourgoignon Flow
Introduction Ricci solitons as a generalization of Einstein manifolds introduced by Hamilton in mid 1980s. In the last two decades, a lot of researchers have been done on Ricci solitons.

On the Cauchy problem for Friedrichs systems on globally hyperbolic manifolds with timelike boundary [PDF]
In this paper, the Cauchy problem for a Friedrichs system on a globally hyperbolic manifold with a timelike boundary is investigated. By imposing admissible boundary conditions, the existence and the uniqueness of strong solutions are shown. Furthermore,

The smallest hyperbolic 6-manifolds [PDF]
By gluing together copies of an all right-angled Coxeter polytope a number of open hyperbolic 6 6 -manifolds with Euler characteristic − 1 -1 are constructed. They are the first known examples of hyperbolic 6 6 -manifolds having the smallest possible volume.

1-efficient triangulations and the index of a cusped hyperbolic 3-manifold [PDF]
In this paper we will promote the 3D index of an ideal triangulation T of an oriented cusped 3‐manifold M (a collection of q ‐series with integer coefficients, introduced by Dimofte, Gaiotto and Gukov) to a topological invariant of oriented cusped ...

Manifolds on the verge of a hyperbolicity breakdown [PDF]
We study numerically the disappearance of normally hyperbolic invariant tori in quasiperiodic systems and identify a scenario for their breakdown. In this scenario, the breakdown happens because two invariant directions of the transversal dynamics come close to each other, losing their regularity.

A Statistical Cohomogeneity One Metric on the Upper Plane with Constant Negative Curvature
we analyze the geometrical structures of statistical manifold S consisting of all the wrapped Cauchy distributions. We prove that S is a simply connected manifold with constant negative curvature K=-2. However, it is not isometric to the hyperbolic space

Dynamical system analysis of a three fluid cosmological model: an invariant manifold approach
The present paper considers a three-fluid cosmological model consisting of noninteracting dark matter, dark energy and baryonic matter in the background of the Friedman–Robertson–Walker–Lemaître flat spacetime.
