Ricci-Bourguignon soliton on three dimensional para-Sasakian manifold [PDF]

Journal of Hyperstructures
In the present paper we study Ricci-Bourguignon solitons on three dimensional para-Sasakian manifolds with potential vector field as a special vector field. We proved the conditions for such manifold to be isometric to hyperbolic space.

Geometrically bounding 3-manifold, volume and Betti number

, 2018
It is well known that an arbitrary closed orientable $3$-manifold can be realized as the unique boundary of a compact orientable $4$-manifold, that is, any closed orientable $3$-manifold is cobordant to zero.

Hyperbolic conformal Ricci solitons and gradient hyperbolic conformal Ricci solitons on bulk viscous fluid string spacetime

European Physical Journal C: Particles and Fields
We explore the Geometrization of hyperbolic conformal Ricci solitons and examine the properties of bulk viscous fluid string spacetime in conjunction with the hyperbolic conformal Ricci solitons in this research note. A $$\varnothing ({\mathfrak {Q}})$$ ∅

Some Results Concerning Hyperbolic Manifolds [PDF]

Proceedings of the American Mathematical Society, 1970
A complex manifold is (complete) hyperbolic if the Kobayashi pseudo-distance is a (complete) distance. In this note, it is shown that a fibre bundle is (complete) hyperbolic if both the base and fibre are (complete) hyperbolic. Two examples are also given.

Existence of conjugacies and stable manifolds via suspensions

Electronic Journal of Differential Equations, 2017
We obtain in a simpler manner versions of the Grobman-Hartman theorem and of the stable manifold theorem for a sequence of maps on a Banach space, which corresponds to consider a nonautonomous dynamics with discrete time.

Cone-manifolds and the density conjecture [PDF]

, 2002
We give an expository account of our proof that each cusp-free hyperbolic 3-manifold M with finitely generated fundamental group and incompressible ends is an algebraic limit of geometrically finite hyperbolic 3-manifolds.Comment: 19 Pages, 2 figures; to

Measure-Expansive Homoclinic Classes for C¹ Generic Flows

Mathematics, 2020
In this paper, we prove that for a generically C1 vector field X of a compact smooth manifold M, if a homoclinic class H(γ,X) which contains a hyperbolic closed orbit γ is measure expansive for X then H(γ,X) is hyperbolic.

Upper and lower bounds on resonances for manifolds hyperbolic near infinity [PDF]

, 2008
For a conformally compact manifold that is hyperbolic near infinity and of dimension $n+1$, we complete the proof of the optimal $O(r^{n+1})$ upper bound on the resonance counting function, correcting a mistake in the existing literature.

Is the Ott-Antonsen manifold attracting?

Physical Review Research, 2020
The Kuramoto model is a paradigm for studying oscillator networks with the interplay between coupling tending towards synchronization and heterogeneity in the oscillator population driving away from synchrony.
