Abstract: In this paper, we investigate solutions to the Diophantine equation A a p + B b p = C c 3 over number fields using the modular method. Assuming certain standard modularity conjectures, we first establish an asymptotic result for general number fields satisfying an appropriate S -unit condition. In particular, we verify that this condition holds for several imaginary quadratic fields. Beyond the asymptotic setting, we also obtain an effective result. Specifically, for the equation a p + d b p = c 3 over K = Q (− d) with d ∈ { 7 , 19 , 43 , 67 } , we determine an explicit bound (depending on d) such that no non-trivial solutions of a certain type exist whenever p exceeds this bound.
