Thin-shell wormholes in N -dimensional F (R) gravity

Abstract

In this work, spherically symmetric thin-shell wormholes with a conformally invariant Maxwell field for N-dimensional F(R) gravity and constant scalar curvature R are built. Two cases are considered: wormholes symmetric across the throat and asymmetric ones having different values of the scalar curvature across the throat. Their stability under radial perturbations is analyzed, finding that unstable and stable solutions are possible for suitable values of the parameters, always made of exotic matter. The stable solutions are found for a short range, slightly over a large critical value of charge.
