Almost Universal Metrics

Metin Gurses, Tahsin Cagri Sisman, Bayram Tekin

A metric is called universal if every symmetric conserved rank-two tensor constructed locally from the metric, the curvature, and covariant derivatives of the curvature is proporti…

Weyl double copy in Lifshitz spacetimes

Gokhan Alkac, Mehmet Kemal Gumus, Mehmet Ali Olpak

Lifshitz black hole solutions pose particular challenges for reconciling the two main formulations of the classical double copy: the Kerr-Schild double copy and the Weyl double cop…

Generalized Vaidya Spacetime in Cotton and Conformal Killing Theories

Metin Gürses, Yaghoub Heydarzade, Çetin Şentürk

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…

Algebra structure of conformal Killing-Yano forms in geometries with skew-symmetric torsion

Ümit Ertem, Özgür Kelekçi, Özgür Açık

We consider conformal Killing-Yano forms corresponding to the antisymmetric generalizations of conformal Killing vectors to higher degree forms in the presence of skew-symmetric to…

Some results on generalized Hukuhara diamond-α derivative and integral of fuzzy valued functions and on time scales

Selami Bayeğ, Funda Raziye Mert, Billur Kaymakçalan

In this paper, we define generalized Hukuhara diamond-alpha integral for fuzzy functions on time scales and obtain some of its fundamental properties and also we establish the rela…

Wave Metrics in the Cotton and Conformal Killing Gravity Theories

Metin Gürses, Yaghoub Heydarzade, Çetin Şentürk

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…
