Title: The matricial range III

Abstract:

The matricial range is a natural generalization of the numerical range studied by Arveson. There is basically a single non-trivial case where it is fully characterized. In this last talk we will talk how Ando used unitary dilations to approach the problem of the matricial range of the 2 × 2 unilateral shift.
