Differential systems involving impulses. (English) Zbl 0539.34001
Lecture Notes in Mathematics. 954. Berlin-Heidelberg-New York: Springer-Verlag. vii, 102 p. DM 19.80; \$ 8.30 (1982).
From the authors’ preface: “An attempt is made to unify the results from several research papers published during the last fifteen years. Chapter 2 contains results on existence and uniqueness (for $$Dx=F(t,x)+G(t,x)Du$$, $$Dx$$, $$Du$$ denote distributional derivatives, $$u$$ is a function of bounded variation and $$Du$$ can be viewed as a Stieltjes measure which has the effect of instantaneously changing the state). In Chapter 3 fixed point theorems and generalized integral inequalities are employed to derive results on stability and asymptotic equivalence. Chapter 4 provides a study for systems
$Dy=A(t)yDu+f(t,y)+g(t,y)Du\quad u(t)=t+\sum^{\infty}_{k=1}a_k H_k(t),$
$$H_k(t)=0,\ t<t_k$$, $$H_k(t)=1,\ t\geq t_ k$$. Chapter 5 deals with extensions of Lyapunov’s second method to the study of impulse systems.”
