In a series of papers, Hiriart-Urruty proposed necessary and sufficient global optimality conditions for the so …-called d.c. problem and the convex maximization problem. In this paper, we investigate the underlying local optimality … conditions, which, in general, are necessary, but not sufficient conditions. We establish sufficient local optimality conditions …
