Reheating in tachyonic inflationary models: Effects on the large scale curvature perturbations
Rajeev Kumar Jain, Pravabati Chingangbam, L. Sriramkumar
We investigate the problem of perturbative reheating and its effects on the evolution of the curvature perturbations in tachyonic inflationary models. We derive the equations gover…
