Simulation of Lattice Gauge Action from the Overlap Operator
  We show the result of the lattice gauge field tensor which is derived from the classical continuum limit of the overlap Dirac operator. By analogous construction, it was recently proposed that the gauge action can be obtained from the overlap operator as well which is proportional to Tr a D_{ov}. We discuss how to carry out Monte Carlo simulations of such a gauge action together with the overlap fermion.
