报告摘要:The aim of this paper is to investigate well-posedness and scalarization for set optimization problems ($l$-SOP) with lower set order via free-disposal sets.Three kinds of well-posedness for ($l$-SOP) via free-disposal sets are proposed, and their relationships are shown. Then, some sufficient conditions for these kinds of well-posedness to ($l$-SOP) are obtained by using the Hausdorff $P$-continuity,  rather than the continuity in the sense of Berge. Furthermore, by employing the nonlinear scalarization technique, the scalar problem $\left( \mathrm{EP} \right) _{\mathcal{D}}$ is established, and the equivalence for solutions between  $\left( \mathrm{EP} \right) _{\mathcal{D}}$ and ($l$-SOP) is also discussed. Moreover, some examples are given to illustrate the main results. Tools and conditions used in this study and the obtained results are different form the existing ones in the literature.
