Perturbative analysis of the gradient flow in non-abelian gauge theories
The gradient flow in non-abelian gauge theories on $ {\mathbb{R}^4} $ is defined by a local diffusion equation that evolves the gauge field as a function of the flow time in a gauge-covariant manner. Similarly to the case of the Langevin equation, the correlation functions of the time-dependent field can …
