The Flat Critical Branch Between Nariai and Bertotti-Robinson Geometries as a Solution of Cosmological Einstein-Maxwell Theory
Metin Gurses, Tahsin Cagri Sisman, Bayram Tekin
We analyze a class of product geometries of the form supported by electric, magnetic, or dyonic flux in the Einstein-Maxwell- theory. These spacet…

Generalized Vaidya Spacetime in Cotton and Conformal Killing Theories
Metin Gürses, Yaghoub Heydarzade, Ãetin Åentürk
We demonstrate that the non-vacuum field equations of Cotton gravity and Conformal Killing gravity admit a generalized class of Vaidya-type solutions. In particular, beyond the sta…

Wave Metrics in the Cotton and Conformal Killing Gravity Theories
Metin Gürses, Yaghoub Heydarzade, Ãetin Åentürk
We study wave metrics in the context of Cotton Gravity and Conformal Killing Gravity. First, we consider pp-wave metrics with flat and non-flat wave surfaces and show that they are…
