The book consists of three parts. In Part A a description of the systems with impulse effect is given. Here are considered systems of the form: \(dx/dt=f(t,x),\) \(t\neq \tau_ k(x)\), \(\Delta x=I_ k(x)\), \(t=\tau_ k(x)\) where f: \({\mathbb{R}}_+x\Omega \to {\mathbb{R}}^ n\); \(\tau_ k: \Omega \to {\mathbb{R}}_+\); \(I_ k: \Omega \to {\mathbb{R}}^ n\); \(\Omega\) is a domain in \({\mathbb{R}}^ n\) and \(0<\tau_ 1(x)<\tau_ 2(x)<...\), \(\lim_{k\to \infty}\tau_ k(x)=\infty\) for \(x\in \Omega\) and are presented theorems of existence, uniqueness and continuability of the solutions; theorems of continuity and differentiability of the solutions with respect to initial data and a parameter. In Part B, Lyapunov’s first method for systems with impulse effect is presented, that is: stability of linear systems, characteristic exponents, stability by linear approximation, perturbation theorems. In Part C, Lyapunov’s second method for systems with impulse effect is developed. The authors prove direct and converse theorems of stability and theorems of comparison using piecewise continuous functions for comparison specially introduced here. The theory is developed in full analytic rigour, and is illustrated by many examples and applications.
