Vaidya-Type Solutions of Quasitopological Gravity Interacting with Nonlinear Electrodynamics

Valeri P. Frolov, Chul-Moon Yoo, Andrei Zelnikov

We construct Vaidya-type solutions of quasitopological gravity coupled to nonlinear electrodynamics in arbitrary spacetime dimensions. Starting from the corresponding static spheri…

Regular Black Holes in Quasitopological Gravity: Null Shells and Mass Inflation

Valeri P. Frolov, Andrei Zelnikov

We investigate the phenomenon of mass inflation in the interior of regular black holes arising in quasitopological gravity (QTG). These geometries are characterized by a bounded cu…

Nonlocal modification of the Kerr metric

Valeri P. Frolov, Jose Pinedo Soto

In the present paper, we discuss a nonlocal modification of the Kerr metric. Our starting point is the Kerr-Schild form of the Kerr metric . Using Newman's a…

Charged Particle Motion Near a Magnetized Black Hole: A Near-Horizon Approximation

Noah P. Baker, Valeri P. Frolov

In this paper, the orbits of a charged particle near the event horizon of a magnetized black hole are investigated. For a static black hole of mass immersed in a homogeneous ma…

Ring wormholes and time machines

Valeri P. Frolov, Pavel Krtous, Andrei Zelnikov

In the present paper we discuss properties of a model of a ring wormhole, recently proposed by Gibbons and Volkov. Such a wormhole connects two flat spacetimes which are glued thro…

Classical mechanics with inequality constraints

Andrei V. Frolov, Valeri P. Frolov

In this paper we discuss mechanical systems with inequality constraints. We demonstrate how such constraints can be taken into account by proper modification of the action which de…
