Optimality conditions for nonsmooth multiobjective bilevel optimization using tangential subdifferentials
RAIRO. Operations Research, Tome 55 (2021) no. 5, pp. 3041-3048

In combining the value function approach and tangential subdifferentials, we establish necessary optimality conditions of a nonsmooth multiobjective bilevel programming problem under a suitable constraint qualification. The upper level objectives and constraint functions are neither assumed to be necessarily locally Lipschitz nor convex.
