Probing symmetric teleparallel gravity in the early universe

Avik De, Dalia Saha, Ganesh Subramaniam +1

General theory of relativity can be equivalently formulated on a flat space-time associating a torsion-free affine connection of non-vanishing non-metricity scalar . In this pap…

How a projectively flat geometry regulates -gravity theory?

Tee-How Loo, Avik De, Sanjay Mandal +1

In the present paper we examine a projectively flat spacetime solution of -gravity theory. It is seen that once we deploy projective flatness in the geometry of the spacetime…

Periodic cosmic evolution in gravity formalism

Parbati Sahoo, Avik De, Tee-How Loo +1

We study the periodic cosmic transit behavior of accelerated universe in the framework of symmetric teleparallelism. The exact solution of field equations is obtained by employing…

A complete study of conformally flat pseudo-symmetric spacetimes in the theory of F(R)-gravity

Avik De, Simran Arora, Uday Chand De +1

We investigate the geometrical and physical structures of a pseudo-symmetric spacetime with timelike vector under the condition of conformal flatness. We classify it into…

How a conformally flat (GR)4 impacts Gauss-Bonnet gravity?

Avik De, Tee-How Loo, Raja Solanki +1

First and foremost, we show that a 4-dimensional conformally flat generalized Ricci recurrent spacetime is an Einstein manifold. We examine such a spacetime as a solution…

Geodesic Deviation Equation In -Gravity

Jing-Theng Beh, Tee-how Loo, Avik De

In the present paper we study the Geodesic Deviation Equation (GDE) in the modified -gravity theories. The formulation of GDE in General Relativity in the case of the homogen…

A Conformally Flat Generalized Ricci Recurrent Spacetime in F(R)-Gravity

Avik De, Tee-How Loo, Raja Solanki +1

In the present paper we study a conformally flat generalized Ricci recurrent perfect fluid spacetime with constant Ricci scalar as a solution of modified -gravity theory. We…

A flat FRW model with dynamical as function of matter and geometry

Anirudh Pradhan, De Avik, Tee How Loo +1

We revisit the evolution of the scale factor in a flat FRW spacetime with a new generalized decay rule for the dynamic -term under modified theories of gravity. It analyses cert…

Inference of forex and stock-index financial networks based on the normalised mutual information rate

Yong K. Goh, Haslifah M. Hasim, Chris G. Antonopoulos

In this paper we study data from financial markets using an information-theory tool that we call the normalised Mutual Information Rate and show how to use it to infer the underlyi…
