Aspects of nonlinear perturbation theory in cosmology

I will review recent suggestions that nonlinear cosmological perturbations are important in slow-roll inflation models. Closely related issues in pure de Sitter spacetime will also be discussed, with the upshot that a reasonable notion of perturbative consistency directly implies a disturbing absence of nontrivial dynamics in de Sitter spacetime. The scope of the talk will be introductory.
