| Research Abstract |
We considered inflation models, in which an inflaton has a non-trivial kinetic term and/or a non-minimal coupling to gravity, as suggested by superstring theory. We gave the formulae of powerspectra and bispectra of primordial density and tensor perturbations. We also discussed the case that a light field other than an inflaton is responsible for primordial density perturbations.
