Editing Schwinger function (section)

=== Euclidean covariance ===
Euclidean covariance axiom (E1) says that Schwinger functions transform covariantly under rotations and translations, namely:

:<math>S_n(x_1,\ldots,x_n)=S_n(R x_1+b,\ldots,Rx_n+b)</math>

for an arbitrary rotation matrix <math>R\in SO(d)</math> and an arbitrary translation vector <math>b\in \mathbb{R}^d</math>. OS axioms can be formulated for Schwinger functions of fields transforming in arbitrary representations of the rotation group.<ref name=":0" /><ref name="Kravchuk Qiao Rychkov 2021">{{Cite arXiv| last1=Kravchuk | first1=Petr | last2=Qiao | first2=Jiaxin | last3=Rychkov | first3=Slava | title=Distributions in CFT II.
