Title: Center Vortices
Abstract: We review recent progress in understanding the center-vortex picture of confinement for SU(N). A notable development is the spectacular confirmation on the lattice of center-vortex predictions for topological confinement 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 ``string" potential in the adjoint representation, the existence and role of nexuses (solitons which are meeting-points for center vortices whose total flux is zero (mod N), and the role of nexuses in understanding confinement in the d=3 Georgi-Glashow model.
