Kantowski-Sachs Universes sourced by a Skyrme fluid
Luca Parisi, Ninfa Radicella, Gaetano Vilasi
The Kantowski-Sachs cosmological model sourced by a Skyrme field and a cosmological constant is considered in the framework of General Relativity. Assuming a constant radial profil…
Constraints on Covariant Horava-Lifshitz Gravity from frame-dragging experiment
Ninfa Radicella, Gaetano Lambiase, Luca Parisi +1
The effects of Horava-Lifshitz corrections to the gravito-magnetic field are analyzed. Solutions in the weak field, slow motion limit, referring to the motion of a satellite around…
Geometric Theory of the Recursion Operators for the Generalized Zakharov-Shabat System in Pole Gauge on the Algebra sl(n,C)
Alexandar B. Yanovski, Gaetano Vilasi
We consider the recursion operator approach to the soliton equations related to the generalized Zakharov-Shabat system on the algebra sl(n,C) in pole gauge both in the general posi…
On the stability of the Einstein Static Universe in Massive Gravity
Luca Parisi, Ninfa Radicella, Gaetano Vilasi
We consider static cosmological solutions along with their stability properties in the framework of a recently proposed theory of massive gravity. We show that the modifcation intr…
The gravity of light
G. Sparano, G. Vilasi, S. Vilasi
A solution of the old problem raised by Tolman, Ehrenfest, Podolsky and Wheeler, concerning the lack of attraction of two light pencils "moving parallel", is proposed, considering…
Superintegrability in the Manev Problem and its Real Form Dynamics
V. S. Gerdjikov, A. Kyuldjiev, G. Marmo +1
We report here the existence of Ermanno-Bernoulli type invariants for the Manev model dynamics which may be viewed upon as remnants of Laplace-Runge-Lenz vector whose conservation…
