Ye, Xin Tao et Li, Chong, On Basic Constraint Qualifications for Infinite System of Convex Inequalities in Banach Spaces, Acta mathematica Sinica. English series (Print) , 23(1), 2007, pp. 65-76
The BCQ and the Abadie CQ for infinite systems of convex inequalities in Banach spaces are characterized in terms of the upper semi.continuity of the convex cones generated by the subdifferentials of active convex functions. Some relationships with other constraint qualifications such as the CPLV and the Slate condition are also studied. Applications in best approximation theory are provided.
