Abstract

This paper investigates the behavior of warm intermediate inflation for flat isotropic and homogeneous universe in Einstein frame representation of fR gravity In this scenario we study the dynamics of two distinct regimes ie strong and weak constant as well as generalized dissipative regimes In both regimes we find inflaton solution corresponding to scalar potential and then evaluate dimensionless slowroll parameters Under slowroll approximation we formulate scalar and tensor power spectra their spectral indices and tensorscalar ratio for Starobinsky inflationary model and study the graphical analysis of these observational parameters It is concluded that isotropic intermediate inflationary model with constant as well as generalized dissipation coefficient for m=01 and −1 remains compatible with Planck 2015 constraints in both dissipative regimes The inflationary model satisfies warm inflation condition in both dissipation regimes but found to be inconsistent for m=3
