摘要：

We consider slowly rotating Ellis-Bronnikov wormholes and investigate their radial perturbations (l 1/4 0), expanding up to second order in rotation. We present the detailed derivations in the general case, including symmetric and nonsymmetric wormholes. The calculations show that the unstable mode present in the static case becomes less unstable with increasing rotation, until it reaches zero and then disappears. This indicates that wormhole solutions may become linearly mode stable at sufficiently fast rotation.
