    support functions reflects exactly the modal structure on the compact convex sets given by convex combinations and convex hulls of unions. (See Section 3 below for an outline, and [4, 3.7] for details.) Given this algebraic approach to Minkowski’s support functions, and the fact that the set of all convex subsets ofRd forms a

    If you take $K$ to be convex, the support function is, in some sense, a tool for a dual representation of the set as the intersection of half-spaces.

Support function - Encyclopedia of Mathematics

    https://www.encyclopediaofmath.org/index.php/Support_function
    A support function is always convex, closed and positively homogeneous (of the first order). The operator is a one-to-one mapping from the family of closed convex sets in onto the family of closed convex homogeneous functions; the inverse operator is the subdifferential (at zero) of the support function.

Convex function - Wikipedia

    Convex functions play an important role in many areas of mathematics. They are especially important in the study of optimization problems where they are distinguished by a number of convenient properties. For instance, a strictly convex function on an open set has no more than one minimum.
