Magnetic Branes in Brans-Dicke-Maxwell Theory
A. Sheykhi, E. Ebrahimi
We present a new class of magnetic brane solutions in -dimensional Brans-Dicke-Maxwell theory in the presence of a quadratic potential for the scalar field. These solutions…
Thermodynamic instability of charged dilaton black holes in AdS spaces
A. Sheykhi, M. H. Dehghani, S. H. Hendi
We study thermodynamic instability of a class of -dimensional charged dilaton black holes in the background of anti-de Sitter universe. We calculate the quasilocal mass of t…
-Dimensional Lorentzian Wormholes in an Expanding Cosmological Background
E. Ebrahimi, N. Riazi
We discuss -dimensional dynamical wormholes in an evolving cosmological background with a throat expanding with time. These solutions are examined in the general relativity…
Expanding -Dimensional Wormhole Solutions in Brans-Dicke Cosmology
E. Ebrahimi, N. Riazi
We have obtained two classes of -dimensional wormhole solutions using a traceless energy-momentum tensor in Brans-Dicke theory of gravity. The first class contains wormhole…
Wormhole Solutions in Gauss-Bonnet-Born-Infeld Gravity
M. H. Dehghani, S. H. Hendi
A new class of solutions which yields an -dimensional spacetime with a longitudinal nonlinear magnetic field is introduced. These spacetimes have no curvature singularity an…
