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.
