The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We report on the existence of a one parameter family of eBHs which are free of pathologies, provided their magnetic and electric charges are equal.

C2weakest assumption

The assumption that the near-horizon limit analysis and numerical construction yield globally regular, asymptotically flat solutions only when the electric and magnetic charges are set equal.

C3one line summary

A one-parameter family of pathology-free spinning dyonic extremal black holes exists in γ=1 Einstein-Maxwell-dilaton theory when electric and magnetic charges are equal.
