Bianchi type IX cosmological model with perfect fluid in \({\varvec{f}}({\varvec{R}},{\varvec{T}})\) theory of gravity
In this work, we have presented axially symmetric Bianchi type IX cosmological model for perfect fluid with dark energy as a cosmological constant Λ within the frame of \(f(R,T)\) gravity theory. Exact solution of the field equations has been accessed by selecting the functional form \({f\left(R,T\right)=f}_{1}\left(R\right)+{f}_{2}(T),\) and by assuming a power law relation between the metric potentials. Several physical and dynamical behaviours of the model are minutely discussed.

Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations
Quantum field theory in curved spacetime
Non-commutative geometry and gravitation
Experimental gravity, in particular tests of general relativity
The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
