**Title: ***
Periodic Orbit Continuation in Multiple Time Scale Systems
*

**Abstract:**
Continuation methods utilizing boundary value solvers are an
effective tool for computing unstable periodic orbits of dynamical
systems. The standard implementation for these procedures is AUTO,
which often requires very fine meshes on problems with multiple
time scales. We will explore alternate strategies based on
geometric singular perturbation theory for computing periodic
orbits in these systems.
