Sign intermixing for Riesz bases and frames measured in the Kantorovich-Rubinstein norm

Nikolai Nikolski, Alexander Volberg

We measure a sign interlacing phenomenon for Bessel sequences $(u_{k})$ in $L^{2}$ spaces in terms of the Kantorovich--Rubinstein mass moving norm $∥ u_{k} ∥_{K R}$ . Our m…
