The following pages are the notes from a seminar that I gave during the spring and some portion of the summer of 1993 at the Mathematics Institute
of Oslo University. The aim of the seminars was to give a rapid but rigorous introduction for the graduate students to Analysis on Wiener space, a subject which has grown up very quickly these recent years under the impulse of the Stochastic Calculus of Variations of Paul Malliavin (cf. [12]).
