Mainly I'm working on the german Wikipedia. Due to my global account there is space for a page here - so I fill it with these lines...

${\displaystyle j^{\mu }=\sum _{i=1}^{N}{\frac {\delta {\mathcal {L}}}{\delta (\partial _{\mu }\phi _{i})}}\varphi _{i}\quad ,\quad \varphi _{i}:=\left.{\frac {\partial \phi _{i}}{\partial \alpha }}\right|_{\alpha =0}}$

(BTW: This Noether current fulfills the Continuity equation :-)

For further details look at my page in german.
