We develop a classical two-dimensional bi-scalar gravity based on the Kaluza–Klein
reduction applied to the four-dimensional Horndeski theory. One of the scalar fields arises …

A bstract By utilizing the ultraspinning limit we generate a new class of extremal vanishing
horizon (EVH) black holes in odd dimensions (d≥ 5). Starting from the general multi …

We investigate dynamics of probe particles moving in the near-horizon limit of (2 N+ 1)-
dimensional extremal Myers–Perry black hole with arbitrary rotation parameters. We …

We investigate dynamics of probe particles moving in the near-horizon limit of extremal
Myers-Perry black holes in arbitrary dimensions. Employing ellipsoidal coordinates we show …

The geometries with SL (2, R) and some axial U (1) isometries are called “near-horizon
extremal geometries” and are found usually, but not necessarily, in the near-horizon limit of …

We consider two solutions of Einstein-Λ theory which admit the extremal vanishing horizon
(EVH) limit, odd-dimensional multispinning Kerr black hole (in the presence of cosmological …

We study geodesics on the near horizon geometry of odd-dimensional Myers–Perry black
hole in the extremal vanishing horizon (EVH) limit. Knowing the fact that geodesics …

We study the hidden symmetries, the symmetries associated with Killing tensors, of the near-
horizon geometry of odd-dimensional Kerr-AdS-NUT black holes in two limits: generic …

We investigate the separability of the Klein-Gordon equation on near horizon of d-
dimensional rotating Myers-Perry black hole in two limits:(i) generic extremal case and (ii) …
