Generalized Schur-Horn orbitopes and zonoids

In this talk I will introduce a special class of convex bodies, the
so-called orbitopes. We will take a closer look at a special class of
orbitopes, namely the Schur-Horn orbitopes and their generalizations which
can be seen as continuous generalizations of permutahedra. We will
introduce the notion of a zonoid which is the continuous generalization of
a zonotope. Since some permutahedra are zonotopes it is a natural question
to ask if there are Schur-Horn orbitopes which are zonoids. We will see
that this is in general not the case.
