Firstly, we present the relationships between the optimal solution sets of primal and dual general vector alpha optimization problems. Secondly, making use of the upper semicontinuity of a set-valued mapping, we discuss the results on closedness of the optimal solution sets for general vector alpha optimization problems in infinite dimensional spaces.</p>}, number={1}, journal={Journal of Nonlinear Analysis and Optimization: Theory & Applications}, author={Su, T. and Hang, D.}, year={2020}, month={Apr.}, pages={1-14} }
