Abstract We obtain numerical solutions for rotating topological solitons of the nonlinear σ -model in three-dimensional anti-de Sitter space. Two types of solutions, i ) and ii ), are found. The σ -model fields are everywhere well defined for both types of solutions, but they differ in their space–time domains. Any time slice of the space–time for the type i ) solution has a causal singularity, despite the fact that all scalars constructed from the curvature tensor are bounded functions. No… Expand

Time Evolution of the Radial Perturbations and Linear Stability of Solitons and Black Holes in a Generalized Skyrme Model
We study the time evolution of the radial perturbation for self-gravitating soliton and black-hole solutions in a generalized Skyrme model in which a dilaton is present. The background solutions wereExpand
SU(3) Einstein-Skyrme solitons and black holes
Abstract In the SU(3) Einstein-Skyrme system static spherically symmetric particle-like solutions and black holes exist for both the SU(2) and the SO(3) embedding. The SO(3) embedding leads to newExpand
