Abstract
As pointed out right after equation (BCV-8) in [1], the symmetric energy-momentum tensor taking part in the Einstein field equations is the negative of the so-called canonical energy-momentum tensor (see also the paragraph following equation (BCV-6) in that paper). Equation (BCV-33) in section 4 of [1] corresponds to the canonical energymomentum tensor, and therefore, the paragraph right before (BCV-33) should better start: In [4], the canonical energy-momentum..., and therefore,
