On perturbations of woven pairs of frames

Published 18 Jan 2021 in math.FA | (2101.07351v3)

Abstract: In this note, we prove some results related to small perturbations of a frame for a Hilbert space $\mathcal{H}$ in order to have a woven pair for $\mathcal{H}$. Our results complete those known in the literature. In addition we study a necessary condition for a woven pair, that resembles a characterization for Riesz frames.
