"Exact and approximate orbit representations of frames"Christensen, OleMotivated by the research topic ``dynamical sampling" we discuss the possibility of representing frames using orbits of bounded operators. Unfortunately only few explicitly known classes of frames have such a representation. The talk will present various methods to circumvent this issue, e.g., by considering approximate representations ``up to machine precision." The new contributions are joint work with Marzieh Hasannasab. |
