Topology and geometry of
infinite dimensional
operators
ABSTRACT
One method of
studying a differential equation is to consider
the geometry and topology of the associated differential operator,
including a study of the critical set, of the various types
of critical points and of the image of the critical set.
In this talk we shall present a survey of some results of this type.
