英文摘要	We investigate whether eternal chaotic inflation can be achieved when the weak gravity conjecture is taken into account. We show that even assisted chaotic inflation with potential lambda phi(4) or m(2)phi(2) cannot be eternal. The effective field theory description for the inflaton field breaks down before inflation reaches the eternal regime. We also find that the total number of e-folds is still bounded by the inflationary entropy for the assisted inflation.
