In a beautiful 1970 original research work, Brevik and Lautrup argue that for a pure radiation field, the space integrals of the time column elements of a canonical energy-momentum tensor constitutes a Lorentz four-momentum; in his well-known 1979 review paper, Brevik argues that Minkowski tensor is an attractive alternative for the description of optical phenomena, because "in a homogeneous medium it is divergence-free" so that its time-column space integrals form a four-vector; in the 2012 work, Brevik and Ellingsen invoke Møller's version of Laue's theorem to support his original argument for Minkowski tensor, because the Minkowski tensor is thought to be a canonical energy-momentum tensor and it is divergence-free for a pure radiation field (while the Abraham tensor is not divergence-free); in the 2013 work, Brevik emphasizes that "it is the Minkowski energy-momentum tensor which is the most convenient alternative to work with, as this tensor is divergence-free causing the total radiation momentum and energy to make up a four-vector"; in the 2016 work, Brevik further emphasizes that "the Minkowski tensor is divergence-free for a pure radiation field, thus leading to a four-vector property of the total energy and momentum"; in a recent Brief Review paper of Modern Physics Letters A, Brevik again emphasizes that Minkowski tensor "is divergence-free, … meaning that the corresponding total momentum components and the total energy form a four-vector"; and in the most recent Editors' Suggestion, Brevik reiterates that "its tensor vanishing four-divergence implies that the energy and momentum photon components constitute a four-vector". However, in all those publications, Brevik did not provide any explanations why the canonical energy-momentum tensor or Minkowski tensor for a pure radiation field satisfies the "zero-boundary condition" required by Møller's version of Laue's theorem; thus leaving readers an open question: Is Møller's version of Laue's theorem applicable to the Minkowski tensor for a pure radiation field?
