    • Instead, one could use a momentum-frequency shell RG [see J. Hertz, Phys. Rev. B 14, 1165 (1976)]. For the problem under consideration, this would lead to a coupling between the large and small frequency degrees of freedom even at the Gaussian level. Since we will conclude that performing the RG transformation on the Gaussian theory is sufficient, this is an unnecessary complication. However, if performed exactly, this more complicated procedure is equivalent to the simpler one we choose to use.
