Résumé |
The inflationary paradigm is most simply realized by a model with a single, slowly rolling scalar field. As
the cosmological data constraining inflation become more and more accurate, it is important to consider
how this benchmark model is located in a theory space of more complicated models. To this end, I will
present a few not-too-complicated examples of multi-field inflationary scenarios in which the relations
between the observations and the model parameters can be quite different than in the simplest case.
