The classical Melnikov method provides information on the behavior of
deterministic planar systems that may exhibit transitions, i.e. escapes
from and captures into preferred regions of phase space. This book
develops a unified treatment of deterministic and stochastic systems
that extends the applicability of the Melnikov method to physically
realizable stochastic planar systems with additive, state-dependent,
white, colored, or dichotomous noise. The extended Melnikov method
yields the novel result that motions with transitions are chaotic
regardless of whether the excitation is deterministic or stochastic. It
explains the role in the occurrence of transitions of the
characteristics of the system and its deterministic or stochastic
excitation, and is a powerful modeling and identification tool.
The book is designed primarily for readers interested in applications.
The level of preparation required corresponds to the equivalent of a
first-year graduate course in applied mathematics. No previous exposure
to dynamical systems theory or the theory of stochastic processes is
required. The theoretical prerequisites and developments are presented
in the first part of the book. The second part of the book is devoted to
applications, ranging from physics to mechanical engineering, naval
architecture, oceanography, nonlinear control, stochastic resonance, and
neurophysiology.
