for over thirty years, symbolic dynamics has been used in celestial mechanics to show the presence of chaos. this paper reviews this history and the more recent attempts at using symbolic dynamics as a method of global analysis in the three - body problem .

even when the continuous dynamics are deterministic, for starters. so why do this ?
- - - mappings into symbols where there is a one - to - one correspondence between continuous states and the symbol sequences they generate. in these cases, studying the symbolic dynamics is completely equivalent to studying the original dynamics. remarkably enough, even with a generating partition, the symbolic dynamics can be stochastic for an underlying deterministic system. in this way, for instance, one can show that some kinds of (sufficiently chaotic) deterministic dynamics are in a sense completely equivalent to sources of independent, identically - distributed random variables .

symbolic dynamics is a rapidly growing area of dynamical systems. although it originated as a method to study general dynamical systems, it has found significant uses in coding for data storage and transmission as well as in linear algebra .

this book is the first general textbook on symbolic dynamics and its applications to coding. it will serve as an introduction to symbolic dynamics for both mathematics and electrical engineering students. mathematical prerequisites are relatively modest (mainly linear algebra at the undergraduate level) especially for the first half of the book. topics are carefully developed and motivated with many examples. there are over 500 exercises to test the reader' s understanding. the last chapter contains a survey of more advanced topics, and there is a comprehensive bibliography .
this is a thorough introduction to the dynamics of one - sided and two - sided markov shifts on a finite alphabet and to the basic properties of markov shifts on a countable alphabet. these are the symbolic dynamical systems defined by a finite transition rule. the basic properties of these systems are established using elementary methods. the connections to other types of dynamical systems, cellular automata and information theory are illustrated with numerous examples. the book is written for graduate students and others who use symbolic dynamics as a tool to study more general systems .
which sets up an opposition between computation, conceived in the usual symbol - manipulation sense, and continuous nonlinear dynamics. this seems to me
[ explains
how to construct signals (time series) of continuous - time dynamical systems that exhibit a given symbolic dynamics. this is achieved without construction of the ordinary differential equations that generate the flow. this construction is of theoretical interest and is useful as a source of dynamical data that can be used to test various data analysis algorithms .

this chapter presents some of the links between automata theory and symbolic dynamics. the emphasis is on two particular points. the first one is the interplay between some particular classes of automata, such as local automata and results on embeddings of shifts of finite type. the second one is the connection between syntactic semigroups and the classification of sofic shifts up to conjugacy .

a useful method for studying discrete - time dynamical systems with continuous state spaces. the basic idea is to take the state space and partition it into a finite number of regions, each of which you label with some symbol. each point in the state space then gives you an infinite sequence of symbols: the symbol for the cell of the partition of the original point, the symbol for the cell of its first iterate, its second, and so forth. normally this involves some loss of information, since you' re going from continuous to discrete values. the symbolic dynamics are often

are drastically simplified. let me introduce some notation here. write \ (x \) for the continuous state, \ (f \) for the map, and \ (\ phi \) for the function taking states to symbols. then the symbol sequence \ (s = \ phi (x) \ phi (f (x) ) \ phi (f ^ 2 (x) ) \ phi (f ^ 3 (x) ) \ ldots \). now suppose i started with \ (f (x) \) instead; my sequence would be \ (\ phi (f (x) ) \ phi (f ^ 2 (x) ) \ phi (f ^ 3 (x) ) \ ldots \). so the dynamics on the space of symbol sequences just consists of shifting to the right: \ (s _ 0 s _ 1 s _ 2 \ ldots \ mapsto s _ 1 s _ 2 \ ldots \).

.) this is completely trivial. all of the structure in the problem has been shifted from the map to space of sequences. for instance, certain subsequences may not occur at all, or differ in probability. but we have a lot of tools for studying sets of discrete symbol sequences - - - not just stochastic process theory, but the theory of
