Title: Beurling-Lax-Halmos Theorem and Operator Theory
Speaker: Prof Jaydeb Sarkar ISI Bangalore
Date: 25 October 2013
Time: 3:30 - 4:30 p.m.
Venue: Lecture Hall I, Department of Mathematics
This talk will be an elementary introduction to (Hilbert) module approach to operator theory. We explore the relationship of the classical von Neumann-Wold decomposition theorem and the Beurling-Lax-Halmos theorem for isometries. We will also discuss a unified approach to the invariant subspace problem for bounded linear operators on Hilbert spaces. The talk will be accessible to a general audience including graduate students.
