  This review is a summary of my work (partially in collaboration with Kurt
Schoenhammer) on higher-dimensional bosonization during the years 1994-1996. It
has been published as a book entitled "Bosonization of interacting fermions in
arbitrary dimensions" by Springer Verlag (Lecture Notes in Physics m48,
Springer, Berlin, 1997). I have NOT revised this review, so that there is no
reference to the literature after 1996. However, the basic ideas underlying the
functional bosonization approach outlined in this review are still valid today.
