On quadruples of linearly connected projections and transitive systems of subspaces

Abstract:
We will study conditions under which the images of irreducible quadruples of linearly connected projections give rise to all transitive systems of subspaces in a finite dimensional Hilbert space.

Joint work with Vasyl Ostrovskii and Yuliya Moskaleva.
