Curvature form of Raychaudhuri equation and its consequences: A geometric approach
Madhukrishna Chakraborty, Subenoy Chakraborty
The paper aims at deriving a curvature form of the famous Raychaudhuri equation (RE) and the associated criteria for focusing of a hyper-surface orthogonal congruence of time-like…
Classical and quantum analysis of gravitational singularity from Raychaudhuri equation
Madhukrishna Chakraborty, Subenoy Chakraborty
The present work deals with the Raychaudhuri equation (RE) to examine the space-time singularity both from classical and quantum point of view. The RE has been looked upon in terms…
Cosmological Wormhole: An analytical description
Subenoy Chakraborty, Madhukrishna Chakraborty
An attempt has been made to have an analytical description for possible traversable wormhole in non-static spherically symmetric space-time supported by anisotropic fluid. Both tri…
A study on existence of Wormhole in Lemaitre-Tolman-Bondi model
Subenoy Chakraborty, Madhukrishna Chakraborty
An investigation has been done for possible existence of evolving wormhole (WH) solution in the background of inhomogeneous Lemaitre-Tolman-Bondi (LTB) space-time geometry. Using s…
