摘要
We present a new formulation to deal with the consistency problem of both massive and massless spin-2 fields in a curved spacetime. Using Fierz variables to represent the spin-2 field, we show how to avoid the arbitrariness and inconsistency that exist in the standard formulation of a spin-2 field coupled to gravity. The superiority of the Fierz frame appears explicitly in the combined set of equations for spin-2 field and gravity: it preserves the standard Einstein equations of motion, whilst maintaining the correct degrees of freedom for the spin-2 field.
