A Gaussian determinant with effective dimension has a singular free-energy contribution proportional to after subtraction of cutoff-dependent analytic terms. When is a positive integer, a logarithm replaces the pure power. Differentiating the determinant sufficiently often gives a marginal momentum integral proportional to . For the anisotropic kernel , , so logarithms occur at . These qualify simple homogeneous-power formulas rather than changing the nominal scaling dimensions.
