The Distributional Stress-Energy Quadrupole
Jonathan Gratus, Paolo Pinto, Spyridon Talaganis
We investigate stress-energy tensors constructed from the delta function on a worldline. We concentrate on quadrupoles as they make an excellent model for the dominant source of gr…
Hubble drift in Palatini -theories
L. Del Vecchio, L. Fatibene, S. Capozziello +3
In a Palatini -model, we define chonodynamical effects due to the choice of atomic clocks as standard reference clocks and we develop a formalism able to quantitati…
Extended Cosmology in Palatini f(R)-theories
Paolo Pinto, Leonardo Del Vecchio, Lorenzo Fatibene +1
We consider the cosmological models based on Palatini f(R)-theory for the function f(R)=aR-2bR^2-3c/R, which, when only dust visible matter is considered, is called dune cosmology…
Discrete Relativistic Positioning Systems
Sante Carloni, Lorenzo Fatibene, Marco Ferraris +2
We discuss the design for a discrete, immediate, simple relativistic positioning system (rPS) which is potentially able of self-positioning (up to isometries) and operating without…
