Abstract
We present the discussion of the energy-momentum tensor of the scalar ϕ4- theory on a noncommutative space. The Noether procedure is performed at the operator level. Additionally, the broken dilatation symmetry will be considered in a Moyal-Weyl deformed scalar field theory at the classical level.
