Nov 01, 2016 · Plan of the paper In the present note we focus, for classical YM (Yang–Mills) theories in n-dimensional Minkowski space, on the EMT (energy–momentum tensor, also referred to as stress–energy tensor or stress tensor for short): the components T μ ν of the EMT can be interpreted as follows, e.g. see reference . We find that the two theories are physically equivalent when the matter sources of the gravitational field have a traceless energy-momentum tensor, but otherwise remain distinct. Personal TM Argon laser is also used for facial treatments, for the correction and traceless eradication of imperfections. momentum equation found in most works in the literature whereby one solves for p and ˝ij. More interesting is the second formulation in which we keep working with p0 and the traceless tensor. In this case, if we insert Eq. (3) into (2), we obtain @ˆui @t C @ˆujui @xj D− @p0 @xi C @.˝ij −.1=3/˝kk ij/ @xj Cˆgi; (6) Sep 20, 2007 · Energy–momentum tensors are investigated for the renormalizable noncommutative Grosse and Wulkenhaar scalar field theory.

Similarly, a traceless symmetric conserved energy-momentum tensor can be used to define a conserved dilatation or scaling current without the need for an in ternal part: T µ = x ν T µν .
