Discontinuous normals in non-Euclidean geometries and two-dimensional gravity
Emmanuele Battista, Giampiero Esposito
This paper builds two detailed examples of generalized normal in non-Euclidean spaces, i.e. the hyperbolic and elliptic geometries. In the hyperbolic plane we define a n-sided hype…
First-post-Newtonian generation of gravitational waves in Einstein-Cartan theory
Emmanuele Battista, Vittorio De Falco
In this paper we investigate the gravitational-wave generation problem at the first post-Newtonian order in the context of Einstein-Cartan theory by exploiting the Blanchet-Damour…
Reconstructing wormhole solutions in curvature based Extended Theories of Gravity
Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello +1
Static and spherically symmetric wormhole solutions can be reconstructed in the framework of curvature based Extended Theories of Gravity. In particular, extensions of the General…
Testing wormhole solutions in extended gravity through the Poynting-Robertson effect
Vittorio De Falco, Emmanuele Battista, Salvatore Capozziello +1
We develop a model-independent procedure to single out static and spherically symmetric wormhole solutions based on the general relativistic Poynting-Robertson effect and the exten…
Einstein, Planck and Vera Rubin: relevant encounters between the Cosmological and the Quantum Worlds
Paolo Salucci, Giampiero Esposito, Gaetano Lambiase +38
In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive substance that we call Dark Matter is hidden in the Universe and what is it made of?, th…
Nonsingular bouncing cosmology in general relativity: physical analysis of the spacetime defect
Emmanuele Battista
In this paper, we describe physical effects occurring in the regularized Robertson-Walker spacetime which can reveal the presence of the defect. Our analysis is based on two main p…
