Weaving Frames and Riesz bases

This talk is about woven frames in separable Hilbert spaces. I will start focusing on the finite-dimensional case. We begin by simplifying the problem to bases, for which we obtain a unique characterization. We establish a condition that is both necessary and sufficient for vector reconstruction, which is applicable to Fourier matrices. Furthermore, we show that these characterizations are still valid in the infinite dimensional case, for Riesz bases. Finally, we obtain several results for weaving Riesz bases of translations.
