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 prove the recovery of exact chiral symmetry in the limit of an infinite fifth direction, and derive the effective four-dimensional operator satisfying the Ginsparg-Wilson relation obtained in this limit.

C2weakest assumption

The spectral properties of the Wilson kernel control the size of residual chiral symmetry breaking for any finite fifth-direction extent; if these spectral features are not as assumed, the residual breaking estimates fail.

C3one line summary

Domain wall fermions recover exact chiral symmetry in the infinite fifth-dimension limit and produce an effective 4D operator satisfying the Ginsparg-Wilson relation.
