Holographic entanglement entropy is cutoff-covariant by Jonathan Sorce

“…This procedure is a priori coordinate dependent, and may not be well-motivated in full, covariant general relativity; however, the fact that physically meaningful quantities such as the entanglement entropy can be obtained by such a regulation procedure suggests some underlying covariance. …”
