An important property is established for higher-order weakly generalized adjacent epiderivatives. This corrects an earlier result by Wang and Li 2009 . 1. Introduction The concept of higher-order weakly generalized adjacent epiderivatives is introduced and an important property is given for the derivatives in 1 Proposition . Let E be a nonempty convex subset of X X X0 e E y0 e F x0 . Let F - y0 is C-convexlike on E Ui e E Vi e Ffui C i 1 2 . m - 1. If the set q x - X0 y e Y m m x - X0 y e G - Tepi F X0 y0 U1 - X0 V1 - y0 . . Um-1 - X0 Vm-1 - y0 fulfills the weak domination property for all X e E then F x - y0 c dWmF x0 y0 U1 - X0 V1 - y0 . Um-1 - X0 Vm-1 - y0 X - X0 C. 1 1 For other notations and definitions one may refer to 1 While proving Proposition 1 1 in 1 the authors used the assumption that the F - y0 is C-convexlike see 2 3 on a convex set E which implies cone epi F - x0 y0 is a convex cone In fact the assumption may not hold The following example shows that the case and Proposition 1 1 may not hold where one only takes m 2 2 Journal of Inequalities and Applications Example .
