Persistence of tripartite nonlocality for noninertial observers

We consider the behavior of bipartite and tripartite nonlocality between fermionic entangled states shared by observers, one of whom uniformly accelerates. We find that while fermionic entanglement persists for arbitrarily large acceleration, the Bell-Clauser-Horne-Shimony-Holt inequalities cannot be violated for sufficiently large but finite acceleration. However, the Svetlichny inequality, which is a measure of genuine tripartite nonlocality, can be violated for any finite value of the acceleration.
