Dear all,

next Friday, April 29th, Antonio Lerario (SISSA) will give a seminar about 

"The zonoid algebra".

Abstract: In this seminar I will discuss the so called "zonoid algebra", a construction introduced in a recent work (joint with Breiding, Bürgisser and Mathis) which allows to put a ring structure on the set of zonoids (i.e. Hausdorff limits of Minkowski sums of segments). This framework gives a new perspective on classical objects in convex geometry, and it allows to introduce new functionals on zonoids, in particular generalizing the notion of mixed volume. Moreover this algebra plays the role of a probabilistic intersection ring for compact homogeneous spaces. Joint work with P. Breiding, P. Bürgisser and L. Mathis.

The seminar will take place in Aula De Blasi, Università Tor Vergata, at 14h00. We encourage in-person partecipation, but should you unable to come here is the link to the event on Teams:
