Abstract: Three-forms can give rise to viable cosmological scenarios of inflation and dark energy with potentially observable signatures distinct from standard single scalar field models. When applied to inflation, a three-form can provide a scale invariant scalar perturbations power spectrum and I will discuss the effect on primordial non-gaussianity. Finally I will discuss a
