Comment on "Multi-black holes in Bertotti-Robinson spacetime"
arXiv:2608.04067
Abstract
We point out that the asymptotically Bertotti-Robinson multi-black hole solutions of Einstein-Maxwell theory can be constructed using only three-dimensional sigma-model techniques, without resorting to the monodromy-matrix approach.
