Deriving Hubble slow-roll parameters from an analytic approximate Hubble parameter in Starobinsky inflation provides better accuracy than the potential slow-roll approximation, reducing the inferred e-foldings by more than one for ns=0.9649.
Multi-field fibre inflation in perturbative LVS uses collective dynamics of several moduli to achieve viable cosmology with sub-Planckian individual field ranges given by total range divided by sqrt(n).
Assisted multi-fibre inflation distributes the required field range across several moduli in global CY orientifolds, overcoming single-field Kähler cone obstructions to realize viable inflation.
A memorial review of the Starobinsky inflation model that proposes a deformation for primordial black hole production and discusses superstring quantum corrections plus universal reheating.
