Sazetak:
I will consider an O(N) model on de Sitter. Making use of Stochastic
inflation, which is a nonperturbative scheme for inflationary cosmology, I
will show that a broken symmetry in an O(N) model eventually gets restored.
I will also discuss the asymptotically late state of an interacting scalar
field on de Sitter. If time permits, I will speculate about the relevance
of this study for cosmological perturbations.
