These notes are based on a course which I gave during the academic year
1983-84 at the University of Colorado. My intention was to provide both
my audience as well as myself with an introduction to the theory of
1arie deviations - The organization of sections 1) through 3) owes
something to chance and a great deal to the excellent set of notes
written by R. Azencott for the course which he gave in 1978 at
Saint-Flour (cf. Springer Lecture Notes in Mathematics 774). To be more
precise: it is chance that I was around N. Y. U. at the time'when M.
Schilder wrote his thesis. and so it may be considered chance that I
chose to use his result as a jumping off point; with only minor
variations. everything else in these sections is taken from Azencott. In
particular. section 3) is little more than a rewrite of his exoposition
of the Cramer theory via the ideas of Bahadur and Zabel. Furthermore.
the brief treatment which I have given to the Ventsel-Freidlin theory in
section 4) is again based on Azencott's ideas. All in all. the biggest
difference between his and my exposition of these topics is the language
in which we have written. However. another major difference must be
mentioned: his bibliography is extensive and constitutes a fine
introduction to the available literature. mine shares neither of these
attributes. Starting with section 5).
