摘要：We calculate perturbative renormalization properties of the topological charge, using the standard
lattice discretization given by a product of twisted plaquettes. We use the overlap and clover
action for fermions, and the Symanzik improved gluon action for 4- and 6-link loops.
We compute the multiplicative renormalization of the topological charge density to one loop; this
involves only the gluon part of the action. The power divergent additive renormalization of the
topological susceptibility is calculated to 3 loops.
