Abstract:
The paper discusses the existence of a continuous extension of functions that are defined on subsets of $\mathbb R^n$ and whose values are convex bodies in $\mathbb R^n$. This problem arose in convex geometry in connection with the notion, recently introduced in algebraic geometry, of convex Newton–Okounkov bodies.
