From Geometry to Observation: Gravitational Waves and the Raychaudhuri Equation
Sougata Bhunia, Anubhab Dutta, Debashis Gangopadhyay +1
Gravitational waves (GWs) are independent of any particular theory of gravity. The universality of this notion is highlighted by the Raychaudhuri equation (RE), which is independen…

Non-Affine Extensions of the Raychaudhuri Equation in the K-essence Framework
Samit Ganguly, Goutam Manna, Debashis Gangopadhyay +2
We present a new avenue of the Raychaudhuri Equation (RE) by introducing a non-affine parametrization within the k-essence framework. This modification accounts for non-geodesic fl…
