A note on the noncommutative correction to gravity
An apparent contradiction in the leading order correction to noncommutative
(NC) gravity reported in the literature has been pointed out. We show by direct
computation that actually there is no such controvarsy and all perturbative NC
corrections start from the second order in the NC parameter. The role of
symmetries in the vanishing of the first order correction is manifest in our
calculation.Comment: Revtex, 3 pages, transferred from PRC to PRD, references added, this
