Linearized stability analysis of thin-shell wormholes with a cosmological constant
Spherically symmetric thin-shell wormholes in the presence of a cosmological constant are constructed applying the cut-and-paste technique implemented by Visser. Using the Darmois-Israel formalism the surface stresses, which are concentrated at the wormhole throat, are determined. This construction allows one to apply a dynamical analysis to the throat, considering linearized radial perturbatio...
متن کاملOnce again on thin-shell wormholes in scalar-tensor gravity
It has been recently proved in a general form [1] that no wormholes can be formed in any scalartensor theory (STT) of gravity in which the non-minimal coupling function f(Φ) is everywhere positive and the scalar field Φ itself is not a ghost if matter sources of gravity respect the Null Energy Condition (NEC). In order to construct any viable and stable wormhole solution, attempts have been rec...
متن کاملArithmetic Properties of 1–shell Totally Symmetric Plane Partitions
In 2012, Blecher defined the combinatorial objects known as 1–shell totally symmetric plane partitions of weight n. He also proved that the generating function for f (n), the number of 1–shell totally symmetric plane partitions of weight n, is given by ∑
متن کاملun 2 00 9 More about thin - shell wormholes associated to cosmic strings
Previous analysis about thin-shell wormholes associated to cosmic strings are extended. More evidence is found supporting the conjecture that, under reasonable assumptions about the equations of state of matter on the shell, the configurations are not stable under radial velocity perturbations.
متن کاملPlane Symmetric Solutions of Gravitational Field Equations in Five Dimensions
We present the effective field equations obtained from a generalized gravity action with Euler-Poincaré term and a cosmological constant in a D dimensional bulk space-time. A class of plane-symmetric solutions that describe a 3-brane world embedded in a D = 5 dimensional bulk space-time are given. Paper presented at the 5th Workshop on Quantization, Dualities and Integrable Systems, Pamukkale U...
