Abstract
An inflationary model which satisfies constraints from particle physics and cosmology is presented. The key feature is an SU(5)-singlet field which drives inflation, leads to proper density fluctuations, and solves the strong problem by the invisible axion mechanism. Thus, for the first time, all reservations about the inflationary universe are removed.
