On Connectedness of the Set of Eficient Solutions for Generalized Systems

M. Rahimi, A.P. Farajzadeh, S.M. Vaezpour

In this paper, we first give a density theorem. We will see that, under some suitable conditions, the set of positive proper efficient solutions is dense in the set of the efficient solutions. Finally, we discuss about the connectedness for the set of the efficient solutions of a generalized system.
