Dynamical sampling and approximate frame representations via iterated systems  
Ole Christensen  
Abstract: Dynamical sampling is currently a very active research area, dealing with, e.g.,  representations of frames via iterations of a bounded operator. Unfortunately,  the class of frames having such a representation is small, and only few concrete examples are known. We prove that the restrictions on the standard theory can be removed by considering approximate representations. The talk presents joint work with Dr. Marzieh Hasannasab at TU Berlin.
