Course Objectives

The notion that discontinuity is a property of motion, alongside continuity, is as old as the concept of motion itself. Many mathematicians today agree that both continuity and discontinuity should be taken into account to describe the real world more accurately.

This course is primarily an introduction to the theory of discontinuous dynamical systems. There are some similarities between this course and those on ordinary differential equations. Therefore, we will cover several standard topics, including the description of systems, definitions of solutions, local existence and uniqueness theorems, extension of solutions, and the dependence of solutions on parameters. We will also explore theorems related to periodic solutions and conduct stability analysis.

 


Course Content

General description of impulsive differential equations: Systems with fixed moments of impulses; systems with variable moments of impulses; discontinuous dynamical systems. Linear systems: General properties of solutions; periodic solutions; Floquet theory; adjoint systems. Stability: Stability criterion based on linearization of systems; direct Lyapunov method; B-equivalence; stability of systems with variable time of impulses. Quasilinear systems: Bounded solutions; periodic solutions; quasiperiodic and almost periodic solutions; integral manifolds. Discontinuous dynamical systems and applications.


Course Learning Outcomes

By the end of the course, the student will learn the following components of the theory: 

  • The concept of impulsive differential equations as hybrid systems with continuous and discontinuous compartments
  • Systems with fixed moments of impulses: Existence and uniqueness of solutions; Continuation of solutions
  • Conditions for periodic dynamics;  Linear and quasilinear systems; Floquet theory; Stability analysis
  • Linearization; Continuous and differentiable dependence on the initial data and parameters
  • The method of small parameters
  • Systems with non-fixed moments of impulses; The beating phenomenon; B-equivalence method; Periodic dynamics; Lyapunov stability
  • Almost periodic impulsive systems and discontinuous solutions
