Abstract
In this note, Logamediate inflationary model on the brain by using canonical scalar fields is studied. The equation of motion is calculated in the slow-roll approximation for canonical model. Perturbation parameters of the model are presented and constrained by the Planck observational data. The results are compatible with the observations.
We study the statistical anisotropies generated in the model of hybrid inflation which is gauged under an Abelian gauge field. The model contains the inflaton field, the gauge field and the waterfall field. We are interested in the limit where the curvature perturbations are generated from inhomogeneity at the surface of end of inflation. The predictions of this model for anisotropies in scalar and tensor power spectra and their cross correlation are studied.
