28/10/2009 Tibor Krisztin Global dynamics for delayed monotone feedback

The delay differential equation

x'(t)=-a x(t)+f(x(t-1))

models delayed feedback mechanism
with a monotone, smooth function f.
This simple looking equation can have a very rich  dynamics. In some cases we are able to give a complete description of the geometric structure of the global attractor.
