Abstract

In the present paper, we extend concept of quasi-conjugate f of f on the basis concept was defined by Thach (2011). We introduce the concept of quasi-subdifferential for quasiconvex functions and use this concept to obtain an optimality condition in the form of a generalized KKT for a nonconvex problem.
