Eternal inflation and swampland conjectures

We study if eternal inflation is realized while satisfying the recently proposed string swampland criteria concerning the range of scalar field excursion, |Δϕ| < D·M[subscript P], and the potential gradient, |∇V|>c·V/M[subscript P], where D and c are constants of order unity and M[subscript P]...
