Sn. Lal et al., DUALITY FOR SOME NONDIFFERENTIABLE STATIC MULTIOBJECTIVE PROGRAMMING-PROBLEMS, Journal of mathematical analysis and applications, 186(3), 1994, pp. 862-867
Multiobjective versions of the weak dual theorems for the nondifferent
iable static programming problems treated earlier by Mend and Smart ha
ve been obtained. These are given here under invexity type of assumpti
ons. Later in the sequel we introduce some fractional programming prob
lems and derive a weak duality result for such programs. (C) 1994 Acad
