Extension problems for polynomial valuations on different cones of convex functions are investigated. It is shown that for the classes of functions under consideration, the extension problem reduces to a simple geometric obstruction on the support of these valuations. The results rely on a homogeneous decomposition for the space of polynomial valuations of bounded degree and the support properties of certain distributions associated to the homogeneous components. As an application, an explicit integral representation for valuations of top degree is established.

    math.FA 2025-05 accept novelty 8.0 of 10

    The paper proves a Paley-Wiener-Schwartz theorem for dually epi-translation invariant valuations on convex functions and uses it to classify all closed affine invariant subspaces.
