I have completed my PhD in Science (Mathematics) in the research area of General Relativity & Cosmology from Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur, India. I have graduated in (Mathematics) from St. Francis D' Sales College, Nagpur, India. My specialization is an M.Sc in Pure Mathematics and I am interested in Astrophysics and Space Sciences. I have published in the Chinese Journal of Physics (1), Astrophysics and Space Science (1), IOP Journal of Physics: Conference Series (JPCS) (1) and Journal of Dynamical Systems and Geometric Theories (03).

    Abstract We intend to study a new class of cosmological models in f(R, T) modified theories of gravity, hence define the cosmological constant as a function of the trace of the stress energy-momentum-tensor T and the Ricci scalar R, and name such a model Λ(R, T) gravity where we have specified a certain form of Λ(R, T). Λ(R, T) is also defined in the perfect fluid and dust case. Some physical and geometric properties of the model are also discussed. The pressure, density and energy conditions are studied both when Λ is a positive constant and when Λ = Λ(t), i.e a function of cosmological time, t. We study behavior of some cosmological quantities such as Hubble and deceleration parameters. The model is innovative in the sense that it has been described in terms of both R and T and display better understanding of the cosmological observations.
