Abstract: Using potentials obtained by working on the asymptotic limit of F-theory compactifications on Calabi-Yau fourfoulds with 4-form fluxes, we systematically study the trajectories through which these potentials send the complex structure moduli to infinity. Working within a quintessence scenario, we show that these potentials do not automatically rule out the existence of an accelerated Universe, and we discuss under which circumstances this might be possible. We relate this with the de Sitter Swampland Conjecture and also provide comments on the connections with the Swampland Distance and Weak Gravity Conjectures.
