Lefschetz Operators on Minkowski Valuations

Explore the action of Lefschetz operators on continuous Minkowski valuations in this 22-minute lecture from the Hausdorff Center for Mathematics. Delve into the world of finitely additive operators on convex bodies, including difference body, projection body, and mean section body maps. Learn how Lefschetz operators facilitate movement between valuations of different homogeneity degrees. Discover insights from joint research with Georg C. Hofstätter and Oscar Ortega-Moreno, focusing on Minkowski valuations compatible with rigid motions.
