Birman-Schwinger Formulation of the Faddeev-Popov Zero-Mode Problem
Daniel G. Tedesco
After removing the constant adjoint modes associated with global gauge rotations, we recast the Landau-gauge Faddeev-Popov zero-mode problem in Birman-Schwinger form on a periodic…

Blind Spots of the Zwanziger Horizon Function
Daniel G. Tedesco
We examine the configurationwise relation between the first Gribov horizon, defined by loss of positivity of the Faddeev-Popov operator, and Zwanziger's horizon function, which pro…

Some Remarks on the Spectral Geometry of the Gribov Horizon
Daniel G. Tedesco
We develop a local spectral framework for the Landau-gauge Gribov horizon that distinguishes gauge-orbit projection from degeneracy of the gauge-fixing Hessian. On a flat torus, sp…
