Rainer Sinn (University of Leipzig)
Families of Faces and the Normal Cycle

We study families of faces for convex semi-algebraic sets via the normal cycle. This is a semi-algebraic set similar to the conormal variety in projective duality theory. Families of faces are represented by a finite list of patches. This is joint work with Daniel Plaumann and Jannik Wesner.

Physical attendance in seminars is restricted to 15 participants. Unfortunately this max. number of allowed participants is reached.
