# Noether's first theorem and the energy-momentum tensor ambiguity problem

@inproceedings{Baker2021NoethersFT, title={Noether's first theorem and the energy-momentum tensor ambiguity problem}, author={Mark Robert Baker and Niels Linnemann and Christopher Smeenk}, year={2021} }

Noether’s theorems are widely praised as some of the most beautiful and useful results in physics. However, if one reads the majority of standard texts and literature on the application of Noether’s ﬁrst theorem to ﬁeld theory, one immediately ﬁnds that the “canonical Noether energy-momentum tensor” derived from the 4-parameter translation of the Poincar´e group does not correspond to what’s widely accepted as the “physical” energy-momentum tensor for central theories such as electrodynamics…
