With very minor assumptions, I show that periodic orbits and hyperbolic sets in an ODE persist under singular perturbations of including a delay term. These perturbations change the phase space from finite to infinite dimensions. The results apply to electrodynamics and give new approaches to handle state-dependent, small, nested, and distributed delays.
I will discuss and explain motivations, the new methods, sketches of the proofs, computer assisted proofs, and possible applications. I will end the talk giving some ideas of work in progress and possible future works.
