Center Vortices

We review recent progress in understanding the center-vortex picture of con nement for SU(N). A notable development is the spectacular con rmation on the lattice of center-vortex predictions for topological con nement and the area law in the fundamental-representation Wilson loop. Recent theoretical progress includes: large-N scaling, the heavy-quark potential for SU(3) baryons, the breakable \...

(n,1,1,α)-Center Problem

Given a set  of  points in the plane and a constant ,-center problem is to find two closed disks which each covers the whole , the diameter of the bigger one is minimized, and the distance of the two centers is at least . Constrained -center problem is the -center problem in which the centers are forced to lie on a given line . In this paper, we first introduce -center problem and its constrain...

Stochastic k-Center and j-Flat-Center Problems

Solving geometric optimization problems over uncertain data have become increasingly important in many applications and have attracted a lot of attentions in recent years. In this paper, we study two important geometric optimization problems, the k-center problem and the j-flat-center problem, over stochastic/uncertain data points in Euclidean spaces. For the stochastic k-center problem, we wou...
