Dynamics of a competitive population system with impulsive reduction of the invasive population

Abstract

Biological invasion refers to the phenomenon that some organisms have been accidentally or artificially introduced into the wild. The invasive populations compete with the local population,and cause damage to the local ecosystem. To protect the local ecosystem, the invasive populations should be artificially reduced. Such processes are seldom studied in dynamical models.
