Can Merons Describe Confinement?
  Merons, conjectured as a semiclassical mechanism for color confinement in QCD, are topological charge-1/2, singular solutions to the classical Yang-Mills equations of motion. I will discuss how lattice techniques can extend the study of merons to nonsingular stationary solutions without destroying properties believed to be essential for confinement, and how zero modes can be used to identify these gauge field configurations in stochastic evaluations of the lattice QCD path integral.
