Rotating thin-shell wormhole from glued Kerr spacetimes

Understand

We construct a model of a rotating wormhole made by cutting and pasting two Kerr spacetimes.

• As a result, we obtain a rotating thin-shell wormhole with exotic matter at the throat.
• Two candidates for the exotic matter are considered: (i) a perfect fluid; (ii) an anisotropic fluid.
• We show that a perfect fluid is unable to support a rotating thin-shall wormhole.
