Dual problems of quasiconvex maximisation
Alexander M. Rubinov, Belgin Şimşek · Bulletin of the Australian Mathematical Society · 1995
A conjugacy operation is introduced on the set Q(X) of all quasiconvex lower semicontinuous nonnegative functions vanishing at zero. This operation is used in order to introduce and study a dual problem with respect to a maximisation problem where both constraint and objective functions belong to Q(X).
