presso la Sala delle Riunioni il dott. Patrick Villa dell'Università di Bochum,  terrà un seminario dal titolo:

''On the convex hull of non-compact Kählerian coadjoint orbits''

We will study Kählerian coadjoint orbits of hermitian Lie groups. A
typical example is given by the real symplectic group. I will present
which coadjoint orbits admit a Kählerian structure. It
is known that the momentum image of these orbits onto a compact Cartan
subalgebra are convex polyhedra. The goal of the talk is to understand
the structure of the faces of the
convex hull of these orbits. For example we will show that all faces
are exposed.

Tutti gli interessati sono invitati a partecipare
