I've read two notes on RG flow:


  2. The Renormalization Group, David Skinner

I've also read RG flow on Peskin's. I think have to say I still don't have a clear image of the meaning of RG flow since the notes I've read so far discuss the topic with a particular example mostly with real scalar field. In addition, I read in a paper that there are several different types of RG flow and it makes me even more confused.

Can you suggest me a good reference on RG flow based on more mathematical language? I need to grasp a precise general overview!
