Abstract
A continuum formulation of gauge-fixing resolving the Gribov-Singer ambiguity remains a challenge. Finding a Lagrangian formulation of operational resolutions in numerical lattice calculations, like minimal Landau gauge, would be one possibility. Such a formulation will here be constrained by reconstructing the Dyson-Schwinger equation for which the lattice minimal-Landau-gauge ghost propagator is a solution. It is found that this requires an additional term. As a by-product new, high precision lattice results for the ghost-gluon vertex in three and four dimensions are obtained.

Strengths
- A new view of an old an important problem concerning the comparison of the results from different non-perturbative techniques for gauge dependent Green's functions
- It raises a number of questions and open a new direction of research.
Weaknesses
- Limited access to physical volumes that raise many questions on the authors conclusions.
