maps whose topological entropy is equal to zero (i.e., maps that have
only cyeles of pe- 2 riods 1,2,2, ... ) are studied in detail and
elassified. Various topological aspects of the dynamics of unimodal maps
are studied in Chap- ter 5. We analyze the distinctive features of the
limiting behavior of trajectories of smooth maps. In particular, for
some elasses of smooth maps, we establish theorems on the number of
sinks and study the problem of existence of wandering intervals. In
Chapter 6, for a broad elass of maps, we prove that almost all points
(with respect to the Lebesgue measure) are attracted by the same sink.
Our attention is mainly focused on the problem of existence of an
invariant measure absolutely continuous with respect to the Lebesgue
measure. We also study the problem of Lyapunov stability of dynamical
systems and determine the measures of repelling and attracting invariant
sets. The problem of stability of separate trajectories under
perturbations of maps and the problem of structural stability of
dynamical systems as a whole are discussed in Chap- ter 7. In Chapter 8,
we study one-parameter families of maps. We analyze bifurcations of
periodic trajectories and properties of the set of bifurcation values of
the parameter, in- eluding universal properties such as Feigenbaum
universality.
