The spectral properties of Vandermonde matrices with clustered nodes

Dmitry Batenkov, Benedikt Diederichs, Gil Goldman +1

We study rectangular Vandermonde matrices $V$ with $N + 1$ rows and $s$ irregularly spaced nodes on the unit circle, in cases where some of the nodes are "clustered" togethe…

Super-resolution of near-colliding point sources

Dmitry Batenkov, Gil Goldman, Yosef Yomdin

We consider the problem of stable recovery of sparse signals of the form $F (x) = j = 1 \sum d a_{j} δ (x - x_{j}), x_{j} \in R, a_{j} \in C,$ from their spectral measureme…
