Gauge-invariant spherical linear perturbations of wormholes in Einstein gravity minimally coupled to a self-interacting phantom scalar field
Francesco Cremona, Livio Pizzocchero, Olivier Sarbach
Recently, there has been quite a lot of interest in static, spherical wormhole spacetimes and the question of their stability with respect to time-dependent perturbations. The cons…

On the linear instability of the Ellis-Bronnikov-Morris-Thorne wormhole
Francesco Cremona, Francesca Pirotta, Livio Pizzocchero
We consider the wormhole of Ellis, Bronnikov, Morris and Thorne (EBMT), arising from Einstein's equations in presence of a phantom scalar field. In this paper we propose a simplifi…
