Nongaussian Isocurvature Perturbations from Inflation

We present a class of very simple inflationary models of two scalar fields which leads to non-Gaussian isothermal perturbations with a ``blue'' spectrum, $ng1.$ One of the models is inspired by supersymmetric theories where light scalar fields naturally acquire masses $\ensuremath{\sim}H$ during inflation. Another model presumes that one of the fields has a nonminimal interaction with gravity $\ensuremath{\xi}R{\ensuremath{\sigma}}^{2}.$ By a slight modification of parameters of these models one can obtain either Gaussian isothermal perturbations, or non-Gaussian adiabatic perturbations with $ng1.$
