Jc. Liu, OPTIMALITY AND DUALITY FOR GENERALIZED FRACTIONAL-PROGRAMMING INVOLVING NONSMOOTH PSEUDOINVEX FUNCTIONS, Journal of mathematical analysis and applications, 202(2), 1996, pp. 667-685
Using a parametric approach, we establish necessary and sufficient con
ditions and derive duality theorems for a class of nonsmooth generaliz
ed minimax fractional programming problems containing pseudoinvex func
tions. (C) 1996 Academic Press, Inc.
