This is a sequel to this question.

Who knows a difference between the Lagrangian in SR and GR for a weak gravitational field in non-relativistic case? What is the reason of this difference?

Maybe you could expand your question somewhat? SRT=? GRT=? Can you describe the difference you are looking for with equations? – user1504 May 2 '12 at 23:18
"...Maybe you could expand your question somewhat?.." It's a "sequel" of my previous question:… . "...SRT=? GRT=?.." SRT - special relativity theory. According to this, GRT - general relativity theory. "...Can you describe the difference you are looking for with equations?.." Factor 2 which multiplies the one of summand. I know that Lagrangian in GRT for the weak gr. fields (when tensor's equations reduces to vectors) looks like: L = -mcsqrt(c - v^2/c + varphi/c + 4*varphivu(x)). – user8817 May 2 '12 at 23:27
L = -mcsqrt(c - v^2/c + varphi/c + 4*varphivu(x)/c). – user8817 May 2 '12 at 23:42
