Abstract

We obtain new charged rotating multi–black hole solutions on the Eguchi-Hanson space in the five-dimensional Einstein-Maxwell system with a Chern-Simons term and a positive cosmological constant. In the two-black holes case, these solutions describe the coalescence of two rotating black holes with the horizon topologies of S3 into a single rotating black hole with the horizon topology of the lens space L(2;1)=S3/Z2. We discuss the differences in the horizon areas between our solutions and the two-centered Klemm-Sabra solutions which describe the coalescence of two rotating black holes with the horizon topologies of S3 into a single rotating black hole with the horizon topology of S3.
