Approximate set-valued quadratic ρ -functional inequalities
Zhihua WangAbstract
In this paper, we attempt to deal with two types of set-valued quadratic ρ -functional inequalities, which are related to quadratic type set-valued functional equation. We also discuss the Hyers–Ulam stability of such set-valued quadratic ρ -functional inequalities by applying the fixed point approach.
