Center Regions as a Solution to the Gribov Problem of the Center Vortex Model [PDF]

open access: yesActa Physica Polonica B Proceedings Supplement, 2021
The center vortex model, capable of explaining confinement and chiral symmetry breaking, has been plagued by the lattice equivalent of Gribov copies: different maxima of the gauge functional lead to different predictions of the string tension. It is possible to resolve this problem using center regions, loops evaluating to center elements, as guide for

The Parameterized Hardness of the k-Center Problem in Transportation Networks [PDF]

open access: yesAlgorithmica, 2020
In this paper we study the hardness of the $k$-Center problem on inputs that model transportation networks. For the problem, a graph $G=(V,E)$ with edge lengths and an integer $k$ are given and a center set $C\subseteq V$ needs to be chosen such that $|C|\leq k$.
