The (Fang–) Fronsdal formulation for free fully symmetric (spinor-) tensors rests on ( γ-) trace constraints on gauge fields and parameters. When these are relaxed, glimpses of the underlying geometry emerge: the field equations extend to non-local expressions involving the higher-spin curvatures, a...
