Perspective on completing natural inflation
We present a perspective on the inflation paths in $2-, 3-, cdots, N-$flation models based on the ultraviolet completion in heterotic string theory, where a number of grand unification scale axions are used. The number of non-Abelian gauge groups for a natural inflation is restricted in string compa...
