Every semi-normalized unconditional Schauder frame in Hilbert spaces contains a frame

Pu-Ting Yu

Let $H$ be an infinite-dimensional Hilbert space. We prove that every unconditional Schauder frame for $H$ contains a subsequence that can be normalized to form a frame for $H$ . As…

Uniform discretization of continuous frames

Marcin Bownik, Pu-Ting Yu

Let $H$ be an infinite-dimensional separable Hilbert space and let $(X, d, I^¼)$ be a metric measure space satisfying the doubling and upper Alhfors regularity conditions at small sca…
