| contents | We present a global embedding of the Fibre inflation model in perturbative large volume scenario (LVS) in which the inflationary potential is induced via a combination of string-loop corrections and higher derivative F$^4$-effects. The minimal Fibre inflation model developed in the standard LVS generically faces some strong bounds on the inflaton field range arising from the Kähler cone constraints, which subsequently creates a challenge for realising the cosmological observables while consistently respecting the underlying supergravity approximations. The main attractive feature of this proposal is to naturally alleviate this issue by embedding Fibre inflation in perturbative LVS. |
