First, a Lagrangian formulation is introduced for the corresponding problem. The Lagrangian function is time-dependent, and the problem cannot be approached with classical procedures because it lacks variational symmetries. Therefore, the variational (Formula presented.) -symmetry method is applied to find exact solutions. Variational (Formula presented.) -symmetries are determined for a family of potential functions, which lead to a one-parameter family of exact solutions. The results are applied to particular examples corresponding to some interesting mass functions reported in the previous literature.}, publisher = {Wiley}, keywords = {exact solutions}, keywords = {Liénard equation}, keywords = {position-dependent mass}, keywords = {variational λ-symmetry}, title = {Exact solutions to a family of position-dependent mass damped oscillators from variational λ-symmetries}, doi = {10.1002/mma.9691}, author = {Ruiz Serván, Adrián and Muriel Patino, María Concepción}, }
