Title: New inequalities on mixed volumes of convex bodies and valuations on convex sets.

Abstract: 
Minkowski's mixed volumes of convex sets are a very classical notion in convexity and have been studied extensively for a long time. We present a few new inequalities for them.
The main tool in their proof is the very recent J. Kotrbaty's analogue of the Hodge-Riemann bilinear relations for valuations on convex sets. We will explain its statement and the necessary background from the valuations theory.
