摘要

We consider a recently proposed nonminimal matter coupling in massive gravity and multigravity. We argue that, when formulated in terms of unconstrained vielbeins, this matter coupling contains the primary constraints necessary to remove the Boulware-Deser ghost to all orders away from the decoupling limit.
