Woven weighted exponentials

Rohit Pai, Ivan Rocha, Pu-Ting Yu

Let $f$ and $g$ be nonzero functions in $L^{2} ([0, 1])$ . The \emph{woven weighted exponential system} (associated with $f$ and $g$ ) is defined by $$\Wc(f,g)=\bigset{\set{fe^{2πi nt}}_…

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 $(X, d, μ)$ be a metric measure space satisfying the doubling and upper Alhfors regularity conditions at small scal…
