Frames and Operator Representations

Ole Christensen (DTU)
Tirsdag 9. oktober 2018 14:15–15:00 Aud. G1 (1532-116)

A frame is a family of elements in a Hilbert space which leads to an expansion of arbitrary elements in the space, similar to what is known for orthonormal bases.The talk will consist of two parts: an introduction to general frame theory and a discussion of the recent research topic dynamical sampling. In dynamical sampling the key question is when and how a frame can be represented via iterates of a bounded operator acting on a single element in the underlying Hilbert space. The talk presents joint work with Marzieh Hasannasab.
