  We prove that if a positive closed current is bounded by another one with
bounded, continuous or Hoelder continuous super-potentials, then it inherits
the same property. There are two different methods to define wedge-products of
positive closed currents of arbitrary bi-degree on compact Kaehler manifolds
using super-potentials and densities. When the first method applies, we show
that the second method also applies and gives the same result. As an
application, we obtain a sharp upper bound for the number of isolated periodic
points of holomorphic maps on compact Kaehler manifolds whose actions on
cohomology are simple. A similar result still holds for a large class of
holomorphic correspondences.
