Multi-black holes and instantons in effective string theory
arXiv:gr-qc/9607036 · doi:10.1142/S0218271898000073
Abstract
The effective action for string theory which takes into account non-minimal coupling of moduli admits multi-black hole solutions. The euclidean continuation of these solutions can be interpreted as an instanton mediating the splitting and recombination of the throat of extremal magnetically charged black holes.
