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 construct singly and doubly spinning non-supersymmetric F1--P black ring solutions in five-dimensional supergravity. These black rings have regular horizons and non-zero temperature. ... the doubly spinning solution admits an extremal limit in which the entropy satisfies the relation S= 2 pi J_phi.

C2weakest assumption

A suitable metric and field ansatz exists in five-dimensional supergravity that satisfies the equations of motion, imposes regularity at the horizon, and realizes the specified F1-P charges and spins without singularities.

C3one line summary

Singly and doubly spinning non-supersymmetric F1-P black ring solutions are constructed in 5D supergravity, with the doubly spinning case admitting an extremal limit where entropy S equals 2 pi times the S^2 angular momentum J_phi.
