Classification of LRS Bianchi type I Spacetimes via Conformal Ricci Collineations
Tahir Hussain, Sumaira Saleem Akhtar, Fawad Khan
In this paper, we present a complete classification of Locally Rotationally Symmetric (LRS) Bianchi type I spacetimes according to their Conformal Ricci Collineations (CRCs). When…
