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…

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…
