We describe some recent results on product dynamics involving homoclinic
and heteroclinic cycles and networks. Previously, in joint work with Peter
Ashwin (Exeter), we proved results on products for which at least one
factor was a homoclinic attractor. The analysis involved some surprisingly
subtle connections with metric number theory. We now have a complete
resolution of all the outstanding problems raised in the earlier work. The
analysis is surprisingly delicate.
This research is joint with Alexandre Rodrigues (Porto) and Nikita Agarwal
(University of Houston).
