A no-go theorem for regular black holes
Stefano Chinaglia
In this article we discuss a no-go theorem for generating regular black holes from a Lagrangian theory. We prove that the general solution has always a Schwarzschild-like term $c/r…
Non-polynomial Lagrangian approach to Regular Black Holes
Aimeric Colléaux, Stefano Chinaglia, Sergio Zerbini
We present a review on Lagrangian models admitting spherically symmetric regular black holes, and cosmological bounce solutions. Non-linear electrodynamics, non-polynomial gravity,…
A non-polynomial gravity formulation for Loop Quantum Cosmology bounce
Stefano Chinaglia, Aimeric Colleaux, Sergio Zerbini
Recently the so-called mimetic gravity approach has been used to obtain corrections to Friedmann equation of General Relativity similar to the ones present in loop quantum cosmolog…
A model of regular black hole satisfying the Weak Energy Condition
Stefano Chinaglia
In this article we discuss a star generated by some matter fluid, whose stress-energy tensor is known. We investigate both the maximally symmetric framework, where all the pressure…
A note on singular and non-singular black holes
Stefano Chinaglia, Sergio Zerbini
An attempt is made in order to clarify the so called regular black holes issue. It is revisited that if one works within General Relativity minimally coupled with non linear source…
General Relativity coupled with Non-Linear Electrodynamics: results and limitations
Stefano Chinaglia
We discuss how to generate a black hole solution of the Einstein Equations (EE) via non-linear electrodynamics (NED). We discuss the thermodynamical properties of a general NED sol…
