Many physical problems, particularly in chemical and biological
systems, involve processes that occur on widely varying time
scales. The resulting model is a system that has a singular
perturbation character. Such problems have motivated the development
of much mathematical theory, including classical asymptotic
theory and a geometric theory based on invariant manifolds.
The phenomena that appear in singular-perturbation problems
are subtle, often involving expansions in terms of quantities
that are exponentially small in terms of a small parameter in
the problem. The singular structure of these equations can also
pose formidable numerical challenges. The goal of this workshop
was to explore the connection between the asymptotic and geometric
theories, with a particular emphasis on exponentially small
phenomena, and to bring researchers developing these methods
together with people working on applications in biology, chemistry
and mechanics.
