Kushnir, Alexey; Liu, Shuo (2017). On linear transformations of intersections. Working paper series / Department of Economics 255, University of Zurich.
For any linear transformation and two convex closed sets, we provide necessary and sufficient conditions for when the transformation of the intersection of the sets coincides with the intersection of their images. We also identify analogous conditions for non-convex sets, general transformations, and multiple sets. We demonstrate the usefulness of our results via an application to the economics literature of mechanism design.
