Qh. Ansari et al., On the equivalence of extended generalized complementarity and generalizedleast-element problems, J OPTIM TH, 102(2), 1999, pp. 277-288
In this paper, we derive some equivalences of generalized nonlinear program
s, generalized least-element problems, and extended generalized complementa
rity problems under certain regularity and growth conditions. We also gener
alize the notion of a Z-map for point-to-set maps. Our results extend recen
t results by Schaible and Yao (Ref. 1).
