Tóm tắt:

 A fundamental problem in complex dynamics is to give an asymptotic of the number of isolated periodic points of period n of a (higher dimensional) holomorphic dynamical system as n is large. In this talk we will see how the intersection theory of closed positive currents (precisely theory of density currents) is applied to obtain a sharp upper bound of this number.
