Comment to ``Quantization of FRW spacetimes in the presence of a cosmological constant and radiation''
Paolo Amore, Alfredo Aranda, Mayra Cervantes +2
The quantization of the Friedmann-Robertson-Walker spacetime in the presence of a negative cosmological constant was used in a recent paper to conclude that there are solutions tha…
Strong gravitational lensing from compact bodies: analytical results
Paolo Amore, Mayra Cervantes, Arturo De Pace +1
We develop a non--perturbative method that yields analytical expressions for the deflection angle of light in a general static and spherically symmetric metric. It is an improvemen…
Analytical formulas for gravitational lensing: higher order calculation
Paolo Amore, Santiago Arceo, Francisco Fernandez
We extend to higher order a recently published method for calculating the deflection angle of light in a general static and spherically symmetric metric. Since the method is conver…
Analytical formulas for gravitational lensing
Paolo Amore, Santiago Arceo Diaz
In this paper we discuss a new method which can be used to obtain arbitrarily accurate analytical expressions for the deflection angle of light propagating in a given metric. Our m…
