• Approximation of discrete functions and size of spectrum ﻿

[OWP-2009-17] (Mathematisches Forschungsinstitut Oberwolfach, 2009-03-11)
Let $\Lambda \subset \mathbb{R}$ be a uniformly discrete sequence and $S \subset \mathbb{R}$ a compact set. We prove that if there exists a bounded sequence of functions in Paley-Wiener space $PW_s$, which approximates ...
• Near critical density irregular sampling in bernstein spaces ﻿

[OWP-2013-16] (Mathematisches Forschungsinstitut Oberwolfach, 2013-07-23)
We obtain sharp estimates for the sampling constants in Bernstein spaces when the density of the sampling set is near the critical value.
