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…

Birman-Schwinger Formulation of the Faddeev-Popov Zero-Mode Problem
Daniel G. Tedesco
The paper reformulates the Gribov horizon problem in Landau gauge as a direct spectral condition on a bounded operator derived from the Faddeev‑Popov operator, using a Birman‑Schwi…

Some Remarks on the Spectral Geometry of the Gribov Horizon
Daniel G. Tedesco
The paper develops a local spectral framework for the Landau‑gauge Gribov horizon, distinguishing gauge‑orbit projection from Hessian degeneracy, proves a quadratic‑form index theo…
