arXiv:gr-qc/9908014 · doi:10.1103/PhysRevD.61.024028
Abstract
Majumdar--Papapetrou multi--black-hole solutions of the Einstein--Maxwell equations are considered in four and higher dimensions. The Euclidean action with boundary conditions appropriate to the canonical ensemble is shown to lead to zero entropy.
