Thin-shell wormholes with a double layer in quadratic F (R) gravity

We present a family of spherically symmetric Lorentzian wormholes in quadratic F(R) gravity, with a thin shell of matter corresponding to the throat. At each side of the shell, the geometry has a different constant value of the curvature scalar R. The junction conditions determine the equation of st...
