Abstract

The present project of scientific research concerns about the theory of systems which describe the evolution of process whose continuous dynamics are interrupted by abrupt changes of state. This phenomenon is called impulse. In many natural phenomena, the real deterministic models are often described by systems which involve impulses.This project lies on the investigation of qualitative properties for impulsive semidynamical systems. We intend to study results about attractors for impulsive systems via Lyapunov functions. The mathematical analysis of such systems employs techniques of topological methods and dynamical system theory. (AU)
