Description

Mathematics Colloquium.

Speaker: Bata Krishna Das.

Affiliation: IIT Bombay.

Date and Time: Wednesday 22 January, 04:00 pm - 05:00 pm.

Venue: Ramanujan Hall, Department of Mathematics.

Title: Model of operators and their characteristic functions.

Abstract:

Dilations of Hilbert space operators is a basic and useful tool which is used to understand non-normal operators. In this talk, we will discuss Sz.-Nagy’s unitary dilations of contractions and some of its far reaching consequences in function theory and operator theory. This inparticular will include a functional model for a class of contractions and their charac- teristic functions. If time permits we will also discuss a recently developed multivariate analogue of these notions.
