Over the past five years, through a continually increasing wave of
activity in the physics community, supergravity has come to be regarded
as one of the most promising ways of unifying gravity with other
particle interaction as a finite gauge theory to explain the spectrum of
elementary particles. Concurrently im- portant mathematical works on the
arena of supergravity has taken place, starting with Kostant's theory of
graded manifolds and continuing with Batchelor's work linking this with
the superspace formalism. There remains, however, a gap between the
mathematical and physical approaches expressed by such unanswered
questions as, does there exist a superspace having all the properties
that physicists require of it? Does it make sense to perform path-
integral in such a space? It is hoped that these proceedings will begin
a dialogue between mathematicians and physicists on such questions as
the plan of renormalisation in supergravity. The contributors to the
proceedings consist both of mathe- maticians and relativists who bring
their experience in differen- tial geometry, classical gravitation and
algebra and also quantum field theorists specialized in supersymmetry
and supergravity. One of the most important problems associated with
super- symmetry is its relationship to the elementary particle spectrum.
