Remarks on the Gribov Problem in Direct Maximal Center Gauge [PDF]

open access: yes, 2001
We review the equivalence of maximal center gauge fixing to the problem of finding the best fit, to a given lattice gauge field, by a thin vortex configuration. This fit is necessarily worst at the location of P-plaquettes.

(𝒏, 𝟏, 𝟏, 𝜶)-Center Problem

open access: yes, 2014
Given a set 𝑆 of 𝑛 points in the plane and a constant 𝛼,(𝑛, 1, 1, 𝛼)-center problem is to find two closed disks which each covers the whole 𝑆, the diameter of the bigger one is minimized, and the distance of the two centers is at least 𝛼. Constrained (𝑛, 1, 1, 𝛼)-center problem is the (𝑛, 1, 1, 𝛼)-center problem in which the centers are forced to lie ...
