Remarks on scalable frames

Peter G. Casazza, Laura De Carli, Tin T. Tran

This paper investigates scalable frame in $R^{n}$ . We define the reduced diagram matrix of a frame and use it to classify scalability of the frame under some conditions. We…

Piecewise scalable frames

Peter G. Casazza, Laura De Carli, Tin T. Tran

In this paper we define "piecewise scalable frames". This new scaling process allows us to alter many frames to Parseval frames which is impossible by the previous standard scaling…

The core of a Grassmannian frame

Peter G. Casazza, Ian Campbell, Tin T. Tran

Let $X = {x_{i}}_{i = 1}^{m}$ be a set of unit vectors in $\RR^n$. The coherence of $X$ is $\coh(X):=\max_{i\not=j}|\langle x_i, x_j\rangle|$. A vector $x \in X$ is said to be isolable if…
