Abstract |
We examine a peculiar corner of Bianchi models in which the conformal expansion is intact. Exact general relativistic shear-free solutions with p-form gauge fields are systematically derived and classified according to energy conditions. A self-similar solution in Bianchi type III is identified and shown to be stable with respect to arbitrary homogeneous perturbations. Partly based on Class. Quantum Grav. 35 (2018) 095011 [arXiv:1712.02778]. |
