TITLE: Does the Bergman shift have the transitive algebra property?
Abstract: A transitive operator algebra is an algebra of Hilbert space operators without proper common invariant subspaces. A well-known open problem in operator theory is the invariant subspace problem. It asks whether singly generated unital transitive algebras exist on spaces of dimension larger than 1. The transitive algebra problem asks whether all unital transitive algebras are strongly dense. Curently there are no known examples where this is not the case. A positive answer to the transitive algebra question would imply a positive answer to the invariant subspace problem.
This will be the first of several talks by Professors Richter and Sundberg. We will discuss examples of unital operator algebras that contain the Bergman shift, are not dense, and have no "obvious" common invariant subspaces.
Friday, August 31
COLLOQUIUM
TIME: 3:35 – 4:25 pm
ROOM: Ayres Hall 405
SPEAKER: Vasileios Maroulas
TITLE: Small noise large deviations and applications
ABSTRACT: A novel method of large deviations for infinite dimensional stochastic
dynamical systems will be presented. Examples of large deviations for stochastic flows of diffeomorphisms arising from an image analysis problem, a reaction-diffusion SPDE, and an
optimal filtering problem where the observation process is corrupted by fractional Brownian
noise, will be discussed.
Refreshments will be available in Ayres 401 at 3:15 p.m.
