摘　　要：The thermodynamics and overcharging problem in RN-AdS black holes with a cloud of strings and quintessence are investigated by the absorption of scalar particles and fermions in extended phase space.The cosmological constant is treated as the pressure of the black hole.The parameters related to quintessence and the cloud of strings are treated as thermodynamic variables.We find that the first law of thermodynamics is satisfied and the second law of thermodynamics is indefinite.Furthermore,we find that near-extremal and extremal black holes cannot be overcharged.
