Gravitational energy-momentum pseudo-tensor in Palatini and metric gravity
H. Abedi, S. Capozziello, M. Capriolo +1
We derive the gravitational energy-momentum pseudo-tensor in both Palatini and metric approaches to gravity. We then obtain the related cosmological gravi…
Cosmological perturbations in gravitational energy-momentum complex
Habib Abedi, Amir M. Abbassi, Salvatore Capozziello
Starting from the energy-momentum of matter and gravitational field in the framework of General Relativity and Teleparallel Gravity, we obtain the energy-momentum complex in flat F…
F-term Inflation and RSII Brane Mode
M. Roostaee, Amir M. Abbassi
Considering hybrid F-term inflation in RSII model and using the most recent data from Planck 2018 and in comparison with Planck 2015and WMAP 9-year , we can obtain some interesting…
Cosmological constant influence on cosmic string spacetime
Amir H. Abbassi, Amir M. Abbassi
We investigate the line element of spacetime around a linear cosmic string in the presence of a cosmological constant. We obtain the metric and argue that it should be discarded be…
Density-metric unimodular gravity:vacuum spherical symmetry
Amir H. Abbassi, Amir M. Abbassi
We analyze an alternative theory of gravity characterized by metrics that are tensor density of rank(0,2)and weight-1/2.The metric compatibility condition is supposed to hold. The…
