The program of the Institute covered several aspects of functional
integration -from a robust mathematical foundation to many
applications, heuristic and rigorous, in mathematics, physics, and
chemistry. It included analytic and numerical computational
techniques. One of the goals was to encourage cross-fertilization
between these various aspects and disciplines. The first week was
focused on quantum and classical systems with a finite number of
degrees of freedom; the second week on field theories. During the
first week the basic course, given by P. Cartier, was a
presentation of a recent rigorous approach to functional
integration which does not resort to discretization, nor to
analytic continuation. It provides a definition of functional
integrals simpler and more powerful than the original ones. Could
this approach accommodate the works presented by the other
lecturers? Although much remains to be done before answering "Yes,"
there seems to be no major obstacle along the road. The other
courses taught during the first week presented: a) a solid
introduction to functional numerical techniques (A. Sokal) and
their applications to functional integrals encountered in chemistry
(N. Makri). b) integrals based on Poisson processes and their
applications to wave propagation (S. K. Foong), in particular a
wave-restorer or wave-designer algorithm yielding the initial wave
profile when one can only observe its distortion through a
dissipative medium. c) the formulation of a quantum equivalence
principle (H. Kleinert) which. given the flat space theory, yields
a well-defined quantum theory in spaces with curvature and torsion.
