Exact solutions in gravity with a sigma model source
A. A. Golubtsova, V. D. Ivashchuk
We consider a D-dimensional model of gravity with non-linear "scalar fields" as a matter source. The model is defined on the product manifold M, which contains n Einstein factor sp…
Instabilities of wormholes and regular black holes supported by a phantom scalar field
K. A. Bronnikov, R. A. Konoplya, A. Zhidenko
We test the stability of various wormholes and black holes supported by a scalar field with a negative kinetic term. The general axial perturbations and the monopole type of polar…
Multi-horizon spherically symmetric spacetimes with several scales of vacuum energy
Kirill Bronnikov, Irina Dymnikova, Evgeny Galaktionov
We present a family of spherically symmetric multi-horizon spacetimes with a vacuum dark fluid, associated with a time-dependent and spatially inhomogeneous cosmological term. The…
