“…In conclusion, we would like to mention that cylindrical thin shells in many studies were used not as auxiliary objects needed to reach asymptotic regions but as the main sources of gravity in wormhole solutions, see [138,146,277] and references therein.…”

With the arrival of the era of gravitational wave astronomy, the strong gravitational field regime will be explored soon in various aspects. In this article, we provide a general review over cylindrical systems in Einstein's theory of general relativity. In particular, we first review the general properties, both local and global, of several important solutions of Einstein's field equations, including the Levi-Civita and Lewis solutions and their extensions to include the cosmological constant and matter fields, and pay particular attention to properties that represent the generic features of the theory, such as the formation of the observed extragalactic jets and gravitational Faraday rotation. We also review studies of cylindrical wormholes, gravitational collapse and Hoop conjecture, and polarizations of gravitational waves. In addition, by rigorously defining cylindrically symmetric spacetimes, we clarify various (incorrect) claims existing in the literature, regarding to the generality of such spacetimes.

“…Cylindrical wormholes of the thin-shell class, including those connecting gauge cosmic string submanifolds, i.e. conical geometries, have been extensively studied [29][30][31][32][33][34][35][36][37][38][39][40]. Now we consider an extension of the latter, that is an asymptotically flat thin-shell wormhole (FW) manifold defined as…”

The problem of the electrostatics in conical wormholes is revisited, now improving the background geometries with asymptotical flatness. The electric self-force on a point charge placed at different regions in the spacetime of a conical thin-shell wormhole connecting flat outer submanifolds is obtained and compared with the results of previous works. The study is also carried out in terms of a previously introduced analogy in which the effect of the matter shells on the electric field is reproduced by non-gravitating layers of charge located on the boundary surfaces. Besides, a better insight on the physical effects of a non trivial geometry is obtained by means of a further analysis of the electric fluxes across the wormhole throat and at both spatial infinities. It is found that the throat is traversed by a non-arbitrary and finite electric flux determined by the global topology, which is proportional to the charge of the source, and is characteristic of the asymptotically flat cylindrical wormholes regardless of the details of the throat geometry.

“…The so-called thin-shell wormholes have drawn the attention of the gravitational community, since the exotic matter can be reduced to a minimal amount and be highly confined. In addition to this, the junction procedure also allows to analyze the wormhole dynamics by focusing on the thin shell where the two geometries are joined [5][6][7][8][9][10][11][12][13][14]. Mathematically speaking, these wormholes a e-mail: cbejarano@iafe.uba.ar b e-mail: eiroa@iafe.uba.ar (corresponding author) c e-mail: gfigueroa@iafe.uba.ar are built by cutting and pasting two geometries at the throat (located at the shell), where the corresponding junction conditions are accomplished; a geodesically complete manifold is obtained after the matching.…”

Thin-shell wormholes in $$(2+1)$$-dimensional F(R) theories

We construct a broad family of thin-shell wormholes with circular symmetry in $$(2+1)$$ ( 2 + 1 ) -dimensional F(R) theories of gravity, with constant scalar curvature R. We study the stability of the static configurations under perturbations preserving the symmetry. We present examples of charged thin-shell wormholes which are asymptotically anti-de Sitter at both sides of the throat. We show that stable solutions are possible when suitable values of the parameters are taken.
