# Isolated Invariant Sets and the Morse Index

Share this page
*Charles Conley*

A co-publication of the AMS and CBMS

This volume contains lectures from the Conference Board of
Mathematical Sciences meeting held at the University of Colorado on May
31–June 4, 1976.

The lectures consist of an expository discussion of basic results for
topological flows and a somewhat more detailed discussion of isolated invariant
sets and continuation.

The construction of the index for isolated invariant sets is new and allows
more general application than previous ones. Also, the index itself is endowed
with more structure and the continuation theorem is modified to take this new
structure into account.

Some elementary applications are given, but the main emphasis is on the
abstract theory.

Every once in a while in mathematics, a strikingly original work appears which radically changes a particular field … [this book] fits this description, the area being the qualitative theory of nonlinear differential equations.
