What is the moduli space of a QFT? What does it mean exactly that there are different inequivalent vacua? Can someone give a precise definition of the moduli space, and some easy examples? And why ...
In the paper of Intriligator, Seiberg, and Shih from 2007, they give an expression for the effective potential on the pseudo-moduli space $X$, estimated at large $X$ (equation 1.3). In this equation, ...
I'm curious what the precise definition of the moduli space of a QFT is. One often talks about the classical moduli space, which then can get quantum corrections. Does this mean the quantum moduli ...
