Born-Infeld gravity with a Brans-Dicke scalar

Soumya Jana, Sayan Kar

Recently proposed Born-Infeld (BI) theories of gravity assume a constant BI parameter ( $κ$ ). However, no clear consensus exists on the sign and value of $κ$ . Recalling the Brans-Di…

Gravitational lensing by scalar-tensor wormholes and the energy conditions

Rajibul Shaikh, Sayan Kar

We study gravitational lensing by a class of zero Ricci scalar wormholes which arise as solutions in a scalar-tensor theory of gravity. An attempt is made to find a possible link b…
