<p>The quantum field theory generalisation of Noether's theorem about symmetries and conservation laws is the Ward-Takahashi identity.
What is a suitable treatment of this in the context of differential geometry and a modern setting?
Thanks</p>

<p>What is a good reference for a geometric version of Noether's theorem about Lagrangians, symmetries and conserved currents?</p>

<p>What is a good reference for a geometrical viewpoint on the calculus of variations for physics, using differential forms etc. to derive Yang-Mills equations and other topics of the standard model?
Thanks for ideas.</p>
