On the interactions and equilibrium between Einstein-Maxwell-Dilaton black holes
Ulrich K. Beckering Vinckers, Tomas Ortin
We study the interactions and the conditions for the equilibrium of forces between generic non-rotating black holes of the Einstein-Maxwell-Dilaton (EMD) theory. We study known (an…
