The equation takes a form of two-dimensional partial differential equation for the multi-fermion effective interactions $V(x,t)$ where $x$ is $\\bar\\psi\\psi$ operator and $t$ is the logarithm of the renormalization scale. The D$\\chi$SB occurs due to the quantum corrections, which means it emerges at some finite $t_{\\rm c}$ in the mid of integrating the equation with respect to $t$.
