Title: Characteristic function of row contractions and colligations

Date and Time: 24th May 2023 and Time : 16.00 hrs

Venue : PSB 3201 (Seminar Hall)

Abstract: We show that the characteristic function of lifting is a complete invariant for liftings of row contractions. A certain class of colligations with defect spaces of finite dimension is characterized. Transformations of the characteristic function of lifting based on the Blaschke factor are studied.
