Gaussian curvature of spherical shells: A geometric measure of complexity
Sayuri Singh, Dharmanand Baboolal, Rituparno Goswami +1
In this paper we consider a semitetrad covariant decomposition of spherically symmetric spacetimes and find a governing hyperbolic equation of the Gaussian curvature of two dimensi…
Conformal Symmetries of Locally Rotationally Symmetric Spacetimes
Sayuri Singh, Rituparno Goswami, Sunil D. Maharaj
In this paper we investigate conformal symmetries in Locally Rotationally Symmetric (LRS) spacetimes using a semitetrad covariant formalism. We demonstrate that a general LRS space…
Rotating and spatially twisting Locally Rotationally Symmetric Spacetimes in f(R)-Gravity: a No-Go theorem
Sayuri Singh, Amare Abebe, Rituparno Goswami +1
Recently, in a series of papers, we established the existence and found a general solution for the simultaneously rotating and twisting locally rotationally symmetric spacetimes in…
Rotating and twisting locally rotationally symmetric spacetimes: a general solution
Sayuri Singh, George F. R. Ellis, Rituparno Goswami +1
In this paper we derive a general solution for the most general rotating and twisting locally rotationally symmetric spacetimes. This is achieved in three steps. First we decompose…
New class of LRS spacetimes with simultaneous rotation and spatial twist
Sayuri Singh, George F. R. Ellis, Rituparno Goswami +1
We establish the existence and find the necessary and sufficient conditions for a new class of solutions of Locally Rotationally Symmetric spacetimes that have non vanishing rotati…
