Title:
Effect of impulsive control in a population model over a patchy environment

Abstract:

In the real world, species often are subjected to instant changes or abrupt perturbations of man-made or natural at some fixed times, which can often be characterized mathematically in the form of impulses, have recently been also studied extensively. Meanwhile, Species dispersal in two or more patches is one of the most prevalent phenomena of nature. Many interesting works and monographies on population dynamics with diffusion have been done. However, in most of these studies till now, it is rarely to consider dispersal species with impulses, which is also one of the most prevalent phenomena of nature. In this talk, we shall propose one model to describe the dispersal species systems with impulses. Dynamical behaviors on extinction and persistence of the systems are investigated and the threshold value is given to determine whether the system is extinct or persist.
