 This book contains two fundamental papers. The first is, in essence, a short monograph devoted to the theory of periodic motions in singularly perturbed systems. The second deals with structural properties of the solutions of a system having infinitely many switchings on a finite time interval to Hamiltonian systems with discontinuous righthand side. Readership Research mathematicians. Table of Contents  E. F. Mishchenko and A. Yu. Kolesov  Asymptotic theory of relaxation oscillations
 M. I. Zelikin and V. F. Borisov  Regimes with increasingly more frequent switchings in optimal control problems
