Talk:Quantum Field Theory/QFT Schwinger-Dyson

There is a missing closing bracket in one of the paragraphs. I'm not 100% sure where the intention of closing it was, so thought best to point it out to someone who will be.

If J (called the source field) is an element of the dual space of the field configurations (which has at least an affine structure because of the assumption of the translational invariance for the functional measure then, the generating functional Z of the source fields is defined to be: 142.157.61.184 (talk) 19:13, 9 April 2010 (UTC)
