On the existence of conformal Killing horizons in LRS spacetimes
Abbas M. Sherif
Let be a locally rotationally symmetric spacetime, and a conformal Killing vector for the metric on , lying in the subspace spanned by the unit timelike direction and…

Thermodynamics with conformal Killing vector in the charged Vaidya metric
Seoktae Koh, Miok Park, Abbas M. Sherif
We investigate the charged Vaidya spacetime with conformal symmetry by classifying the horizons and finding its connection to Hawking temperature. We find a conformal Killing vecto…

Existence of gradient CKV and gradient conformally stationary LRS spacetimes
Seoktae Koh, Abbas M Sherif, Gansukh Tumurtushaa
In this work, we study the existence of gradient (proper) CKVs in locally rotationally symmetric spacetimes (LRS), those CKVs in the space spanned by the tangent to observers' cong…
