A note on constraint qualification for saddle point conditions involving convex and linear affine functions
摘要
We take into consideration the classical saddle point conditions for programming problems involving convex functions, linear affine functions and a convex set constraint. We prove a nonlinear theorem of the alternative, and we discuss the relationships between the Slater constraint qualification and a constraint qualification proposed by Neustadt (Neustadt LW. Academic Press, New York, pp 323–348,1970) .
