Abstract
In this Letter, we investigate the possible theoretical constraint on the parameter n of the agegraphic quintessence model by considering the requirement of the weak gravity conjecture that the variation of the quintessence scalar field Ï should be less than the Planck mass Mp. We obtain the theoretical upper bound nâ²2.5 that is inconsistent with the current observational constraint result 2.637
