The Continuity of $\mathbb{Q}_+$-Homogeneous Superadditive Correspondences

In this paper we investigate the continuity of $\mathbb{Q}_+$-homogeneous superadditive correspondences defined on the cones with finite basis in real topological vector spaces. It is also shown that every lower semicontinuous and $\mathbb{Q}_+$-homogeneous superadditive correspondence between two cones with finite basis admits a family of continuous linear selections.
