A no-hair theorem for black holes in f(R) gravity
(Institute of Physics Publishing, 2018)
In this work we present a no-hair theorem which discards the existence of four-dimensional asymptotically flat, static and spherically symmetric or stationary axisymmetric, non-trivial black holes in the frame of f (R) ...
Comparative statics, english auctions and the Stolper-Samuelson theorem

Static limit analysis of reinforced soil structures by a simple finite element and second-order cone programming

QUANTUM SINGULARITIES IN STATIC SPACETIMES

Pseudo Focal Points Along Lorentzian Geodesics and Morse Index
(ADVANCED NONLINEAR STUDIES, INC, 2010)
Given a Lorentzian manifold (M,g), a geodesic gamma in M and a timelike Jacobi field Y along gamma, we introduce a special class of instants along gamma that we call Y-pseudo conjugate (or focal relatively to some initial ...
Nonexistence theorems for traversable wormholes

Birkhoff's theorem in Lovelock gravity for general base manifolds
(2015)
We extend the Birkhoff's theorem in Lovelock gravity for arbitrary base manifolds using an elementary method. In particular, it is shown that any solution of the form of a warped product of a two-dimensional transverse ...
Bopp-Podolsky black holes and the no-hair theorem
(Springer, 2018-01-19)
Bopp-Podolsky electrodynamics is generalized to curved space-times. The equations of motion are written for the case of static spherically symmetric black holes and their exterior solutions are analyzed using Bekenstein's ...
Weak lensing in a plasma medium and gravitational deflection of massive particles using the Gauss-Bonnet theorem: A unified treatment
(American Physical Society, 2018-06-08)
We apply the Gauss-Bonnet theorem to the study of light rays in a plasma medium in a static and spherically symmetric gravitational field and also to the study of timelike geodesics followed for test massive particles in ...
