on optimality conditions for composite uncertain multiobjective optimization

This article is concerned with a nonsmooth/nonconvex composite multiobjective optimization problem involving uncertain constraints in arbitrary asplund spaces. we first establish necessary optimality conditions for weakly robust efficient solutions of the problem in terms of the limiting subdifferential. then, sufficient conditions for the existence of (weakly) robust efficient solutions to such a problem are driven under the new concept of pseudo-quasi convexity for composite functions.
