I am trying to construct dynamical landau theory for self-assembly. From my constructed landau energy functional i derive dynamical equations using model-A of hohenberg and halperin. I solve those ...

From vertex function to anomalous dimension

In a $d$ dimensional space-time, how does one argue that the mass dimension of the $n-$point vertex function is $D = d + n(1-\frac{d}{2})$? Why is the following equality assumed or does one prove ...
